I don't mind the channels I like having sponsors, and if I do I just double tap forward a couple of times to skip the minute.
Every time I see a creator I like do a "smooth transition" from content to ad, it makes me feel betrayed. Not only are they about to read words someone else wrote for them and which they don't really believe, they spent an extra 15 seconds pretending it was part of the video in order to keep my full attention when they throw the sponsor name in my face. It's scummy behaviour.
Creators need sponsors to pay the bills, just as they do ads, I get it. I don't fault them for the industry basically forcing them into these kinds of "integrated ad reads", as well as the fact basically all the sponsors have huge ethical problems. But I will not subject myself or the people who watch videos with me or on my devices to this brain rot.
That's why I try to support them in other ways (YouTube Premium, Patreon, etc.) and run adblock and sponsorblock on everything. By my napkin math, they make more this way anyways.
Unless the goal of the spot is literally just "Our name exists!!" which tbf it probably is for all those VPN ads, it doesn't really make a whole lot of sense.
Surely nobody watches the full ad segments?
A great example of this is Raid Shadow Legends. They were sponsoring what felt like every channel, to the point where it became a meme. But at some point, someone is going to go through the app store looking for an app to help with their boredom and is going to see Raid, at which point their subconscious says "I know that name. I should check it out."
How is that LESS annoying?
If I notice they are starting to again mention that VPN client or whatever I can just decide to skip (and the visuals often change as the "ad" is often prerecorded). But I remain in control.
For comparison: say you're getting a haircut. And halfway they stop cutting to promote their new book, for 5 minutes straight. Telling you they would not be able to provide you with the haircut if they cannot promote the book.
