Well, there's an overlap with the Mario rom hacking community - or the Mario community in general. I remember the Stardew Valley community to be also quite welcoming.
I do have Google Messages on my phone, as the pre-installed SMS app doesn't support RCS (or maybe just doesnt want to talk to the RCS implementation of my mobile network). I tried a few alternatives, but all didn't want to enable RCS on the mobile network that I'm on or had some other major problems. Google Messages just worked.
Since today, I cannot access the app without a login. I cannot proceed and access my messages unless I login. It's not just the Google features as you state, the whole app is now useless.
Aragorn: Gentlememe! We do not meme 'til nightfall.
Pippin: But what about memefast?
Aragorn: You've already had it.
Pippin: We've had one, yes. But what about second memefast? Aragorn stares at him, then walks off.
Merry: Don't think he knows about second memefast, Pip.
Pippin: What about elevenmemes? Lunchmeme? Afternoon meme? Dinner meme? Supper meme? He knows about them, doesn't he?
Merry: I wouldn't count on it Pip.
Yeah, but now you’re talking about communicating with web.archive.org and not nonesense.reputable-bank.com as in the original post. In this case you’re not even trying to hide the fact, that you aren’t affiliated with reputable-bank.com and we're back to square one and you could also just use reputable-bank.com.some.malicious-phishing.website to host your page.
Btw: all modern browsers will warn you when you access a non-encrypted website - some immediately, some only when you try to enter data into a login form.
