A company goes through an enormous amount of careful work to release a product that works beautifully and elegantly, and exactly in the manner it was designed.... and you want to blame them for not ALSO bending over backwards to provide that same level of elegance and functionality on multiple antagonistic competitors' platforms?

I get your current irritation with MMS is very present in your mind. That sucks. But applying fault and blame solely to one party for a fouled up transaction - when the execution of that transaction involves at least three intermediate vendors with extraordinarily shitty platforms - is just not reasonable.

And the App Store/iTunes hate? It's a curated, gated community. You know that when you buy in to it, and that's part of the attraction. There are plenty of other options that have mountains of toxic shit you can install on a whim. Feel free to live there. I don't choose to. In my estimation, my time is more valuable than that.

(Footnote: My wife and I have been texting between iPhone and Android for close to 10 years now, without a hitch. And she HATES to upgrade, and is often using tech 5 years old, or more.)
