Google has historically done a lot of good things. Today they simply do evil, but pushing for RCS adoption when telcos refused to is one of those good things they did.

You can still hate Google and want them to disappear, I do, but that doesn't mean you automatically hate everything ever touched by them. Their motivation may have been strictly to compete with Apple, but e2ee messages are a net positive if you must use it. Use signal and matrix when you can, use RCS when you must.
