I think that there is a misunderstanding about the purpose Beeper is trying to solve. It’s about consolidating all your chat services together into one place. Google messages is SMS/MMS/RCS. Beeper or by extension the whole matrix platform with bridges can roll almost all your services together, gchat, sms, mms, RCS, Facebook, iMessage, discord, WhatsApp, signal, telegram, slack, instagram, etc.

I’m guessing this prevents android messages from coming through as green, which for some reason paints you as a social pariah.

You clearly didn’t read the full article or don’t understand everything this does.
