This is true of many phones over time.
You dont legislate who is going to buy the phone, but you do focus the products towards a specific need.
It didnt start today. For example products as far back as the Nokia E series and Blackberries were designed around needs of business users as a primary target group, but other people bought the device too.
That is what is going on in with the Note. It would make no sense to cripple the phone, there is already a crippled Galaxy A7 and the smaller Galaxy S and Galaxy Alpha series also crippled.
So there just would be no point in offering a wide product range and then crippling all of them. In that case you might as well save your time and cut down the number of products offered.
Ding ding ding!! We have a winner! This has been a criticism of Samsung for years--far too many products, no apparent direction. Seems like they may be listening.
Seriously though, what you find to be 'crippled', the vast majority of people just don't care about. They don't swap batteries, and I'd wager quite a significant number aren't even aware memory is expandable. There's a reason Samsung, the longtime bastion of these features, is finally moving away from them--most customers don't care about them, they actually care quite a bit more about aesthetics and design, and Samsung will now be able to do exactly what Apple has done for years, make more money by overcharging for additional memory. The proof about the first two points will be how many more S6 devices are sold vs. the S5.
And even if they were worried about potentially alienating customers, where else are they going to go? All OEMs are moving in this direction, or already have.
