Whole situation reminds me of another one. When Google created their services to be unavailabe to install without root access, while Huawei locked their devices so device owner have no root access that Huawei has remotely.

Then people started blaming regulators for inability to have Play Store on Huawei branded phone, not questioning why blessing from device vendor to install an app is required in the first place.

Matrix with bridges and bots all the way.

My only issue with RCS is that it requires that either LTE or wifi be on. I personally keep those off unless I want to actively use the internet. Not a big deal, minor annoyance though.
