Grayjay only supports Android, so let me mention Tube PiP for iOS

It depends where you live really. It’s a problem in the US indeed but for instance in many countries in Europe they don’t sexually harass their females on a “day-to-day basis”

The article doesn’t mention a monthly fee though

Half of the Tesla vehicles are made in China, they are not competing with the Chinese EVs but they are the Chinese EVs themselves instead

Yeah I just hope they move their operations to some more democratic country since their location in the US apparently doesn’t help them anyways

I’m afraid there aren’t any. You can use the Bypass Paywalls Clean extension though

Most of the possible contenders lack video calls and some also other needs mentioned by the OP. Nextcloud Talk has them all

Mind you that they keep paywalling previously free features. Example of them paywalling group calls and their Playbooks feature (v1 - generally available, v2 - in paid plans only): https://docs.mattermost.com/product-overview/mattermost-v10-changelog.html

Nextcloud Talk - actually free and fully-fledged unlike the alternatives that either require you to pay money or don’t support more advanced features like video calls
