The post you link to says your reasons for using it are personal so they do not apply to anyone but you. It is really easy to use YouTube yourself while posting links to Invidious. Alternatively, only some of the reasons in that post are personal. I can only see point number one as a reason to recommend YouTube above Invidious. For point number two and three, the same content that exists on ThemTube is on Invidious, so the ideas on there are the same, so no reason to promote YouTube above Invidious there. In fact, some of the content that would be region-blocked or age restricted on YouTube would be easily accessible on Invidious, so points two and three actually favour linking to Invidious. Regarding point number four, I cannot believe a decline in quality is a reason to use something. The rest of the points are obviously personal. Is it really worth supporting the Google corporation (and making others do the same) just for a better media player? The Invidious player isn't all that bad and the features you state (speed, resolution and playback) can all be customised on Invidious' player.
