I've found that my circle of contacts use the default messaging app for group chats even more now. I couldn't get them to use Signal but at least they're posting in the RCS group chat more instead of on Meta platforms.

A good rule of thumb is : does any of the participant maintain the backend?

If not then you are dependent on at least a 3rd party. If that 3rd party is not entirely open, meaning at least

  • standards for the protocol,
  • open source for the backend and frontend,
  • alternative clients,
  • alternative backends,
  • both can be actually used (not just in theory because the protocol has been published)

then basically you should consider that this 3rd party owns your group, there is no expectation of privacy in it, it can be closed in an instant, messages can be modified without you knowing it, etc.

TL;DR: bad.
