Hi.
I signed up an account just to share my views on this matter!
As a person who has a desktop PC that's not Apple, a Macbook Air mid-13 and an iPad (5th gen, I think?), I get some of the hate people have towards Apple.
Although iPhone was not the first touch screen phone and iPad was not the first tablet, they were implemented so much better than their respective competitors that you might as well consider iPhone and iPad were the first smartphone and tablet. But that's about it.
I am irritated that some of the features the other products had before their Apple counterparts are presented like they were done by Apple first. Most of the time, someone else already have done what Apple considers 'innovative'. No, what you named iSomething was already being used by other people and it's not invented by you, Apple.
This attitude is magnified with the Apple hardcore fans. Sorry, not hardcore fans, but by iSheep. Hardcore fans are people who knows and understands how Apple operates and considers it fine and they are okay with technology not being led by Apple. iSheep are different kind of people, and they are so oblivious to the life outside Apple that to them, if Apple is not using something, it's because it does not exist and it won't exist until Apple invents it.
In general, Apple is a company who waits for a tech to mature enough to be used seamlessly by the end user and then implements it. Sometimes they implement their own version of it, sometimes they contribute to the maturation process of a tech, sometimes they just wait for it to mature. Of course, sometimes they just invent (or innovate) it. That is totally fine and actually that's what made Apple such a big brand, imo.
Let's be honest here, 99% of the time, a tech is implemented better by Apple than their competitors. Like I said, this was so true with iPhone and iPad that it's not a horrible mistake to think that they are the first products of their lines. Whether they invented something or not, they implement it better than the rest, most of the time.
Apart from that, Apple mostly gets hate for their price, their closed ecosystem, their way of conducting business.
Apple is expensive: So what? They put the price, people buy it. Nobody hates Ferrari because it's expensive, so why hate Apple?
Apple is late to implement new tech: So what? They use older tech, it works, people use it. Want the next tech? Get the device that has it.
Apple uses outdated parts in their computers: So don't buy it.
Apple makes devices that are hard to fix/upgrade: Apple is not your only choice in any of their product line, so get something that you can fix/upgrade later.
Apple has closed ecosystem: That's a decision they made, and if you don't like it, don't buy Apple. If you bought it anyway, you knew what you're jumping into.
Apple devices are not customizable: Some people like to 'just' use their devices. They buy Apple. You want to tinker with your devices, don't buy Apple.
You may be right with your criticism, but it doesn't mean that your hate is justified. It is not.
Apart from the attitude "Apple was here before everyone else", I think the rest of the hate is irrational. You can't hate Apple for being Apple.
Same irrational hate is directed to every popular brand, to be honest. Do we all love Google, Microsoft and Samsung? Do we all criticize them rationally? I've never had a BSOD since Windows 8.1 and I'm using Win 10 on my desktop now, but it's still a thing to hate. People still think that AMD processors will heat to the point of explosion, Samsung users are still hating the TouchWiz interface of their Samsung phones. People still are talking about "you're not holding it right", bending iPhones, exploding Note 7. People are still comparing cheap Android phones to a premium device, the last iPhone. I think internet is to blame here.
BUT, as a person who tried to get into Apple ecosystem, I think Apple is not making the best decisions lately. I could not justify buying iPhone X for the price and features. The smartphone is the missing part for my total integration to Apple ecosystem and despite that, I could not justify buying it. Also, the latest Macbooks are not compelling me to upgrade to one of them although I have the base model of Macbook Air with 128 GB SSD and 4 GB of RAM. I hear that people need some sort of adapter to connect their new iPhones to their new Macbooks and that's disappointing for a company whose biggest selling point is their ecosystem.
