The problem in the US is that the iPhone has a huge amount of the market and iMessage mostly does that already. For Android to counter that you have to use a 3rd party app, which further fractures an already smaller market. Or everyone could just use sms which is free with basically every plan nowadays, which gets you by.
I’ve bought Samsung for the past 5 years now and have never had an issue with bloat if you buy from Samsung. If you’re buying it from a carrier then yeah there’s probably a ton of crap preloaded. Imo Samsung just offers too much of a complete package to pass up. Pixel is good but hardware leaves some to be desired. The cute software quirks just don’t make it up for me.
