> no channel with latest video older than two weeks

Not every tech tuber can crank out a video every 14 days, sometimes you only get one video every 2 months...

> I clicked on a bearded sales guy by mistake and my feed is now full of this guy.

I make copious use of the "Not Interested" and "Don't Recommend Channel" menu items on suggested videos. And I also frequently thumbs-down videos that I watch that I don't want influencing my ranking. Doesn't help completely but I'm generally satisfied with my YT recommendations.

There is no way leaving this unprotected on the open internet goes well.
