At first I saw the sponsor segments, later it became too repetitive so I started doing the double-touch action (skip 10 or 20 seconds forward) when a video would start talking once again about the VPN service of the month (really, it seems to always be VPN services!), and later I ended up having to actually pause the video, scroll forward even a couple minutes (some sponsor segments have gone wild in duration lately).

Then I started using[1] SponsorBlock, and now we're back at square 0.

[1]: I had known about it for a long time but didn't feel like using it, until I did (or you can see it as "they made me feel like using it"...)
