True, good points.
My 3 siblings and I, all use Telegram now, and love it. We all dumped WhatsApp awhile back after the Facebook BS crap they're pulling with it. Telegram works great for the 4 of us, 2 are on iPhone's, and 2 on Android, 3 of us live in the States, 1 lives in Europe part-time. The one Brother living in Europe, we text each other often, just the two of us, and Telegram has been perfect, we'll use it for phone calls and video chat too.
And my immediate family, my Wife, and 2 kids, all have Pixel phones, I have the 12 Pro Max and Pixel 5a, just popped my SIM back in the 12 PM for todays Apple event LOL. I use iMessage to text them, which they all use Google Messages, and zero issues, no problems.
