To actually answer your question: The beef is with green (SMS) text bubbles. iMessage is closer to Discord chats; You can react to messages, edit messages, delete/unsend messages, see read receipts, send messages with spoiler text, draw doodles directly in the chat, send voice memos, send full quality images/videos, share iCloud links natively, send money directly via ApplePay, send animated emojis, stickers, and embedded gifs, etc… But as soon as an android user gets added to the chat, everyone is downgraded to regular SMS texts.

Yes, on the back end it’s largely Apple’s fault for refusing to play nicely with other brands. But that doesn’t change the fact that on the front end the result is a noticeably worse experience for Apple users every time they message an android. The “ugh, green text bubbles” reaction is because they’re missing a lot of features that are built directly into iMessage.

I’m not saying it justifies making dating decisions based on a person’s phone choice. I’m dating someone who has an android, because why wouldn’t I? I’m not dating her for her phone. But some people may use those extra features more than I do, and may end up annoyed every time they have to text that person.

It’d be like if one person in a Discord group chat decided they didn’t want any of the nice features of Discord… So Discord just disabled those features for the entire group chat. Rather than not displaying them to that one person, it just turns them off entirely for the entire chat. So now nobody can use them, even if they wanted to. Naturally, the other people in the group chat may get a little annoyed every time they want to send a gif or react to a text, but can’t.
