IMO, quality wise, sponsored segments advertise better products than the YT ads. In most cases, they are tied to the video/creator and the creator talks and advertises them because they themselves use it. They feel a lot more organic and targeted than anything the YT algo ever showed me.
Well, another problem that I have is that I watch a lot of videos from US-based creators.
For me as a european, quite a lot of physical items which are being sponsored are not available in my country, so the ads for these are essentially useless.
The rest of the ads are VPNs(which I already got), various SaaS which I have absolutely no use for or things I already know (and don't want).
Online ads are already annoying and useless to me, but sponsored segments are even worse.
At least I don't feel bad for skipping these segments because AFAIK, creators just have to integrate these segments into the videos, that's it. The advertisers can't know if I've seen the segment so the creator gets paid the same, doesn't matter if I watch or skip it.
They get paid just for talking about the products, what's the difference if I skip the segment manually, or if a plugin does it automatically?
