For us, we have to watch the unskippable ad during Star Trek Picard, then it jumps back 10 minutes in the episode so we need to fast forward to get back to our place. This has been going on for several episodes.
Ugh I hate that with YouTube ads as well (at least on my Android TV). I'll watch something, get interrupted by ads, sometimes minutes long and/or multiple ads, and after the ad(s) it jumps seconds or even minutes ahead from where I was watching. Then when I rewind to the point I was at it'll often play even more ads. It's super annoying but if they think this convinces me to buy their premium subscription they're very wrong. It's so off-putting.
If you pay for the streaming service and it doesn't let you watch the content how it should then you're perfectly justified to just download a copy, nothing savage about that.
Provided it's available in your location, and still being sold/produced. Furthermore Blurays are only going to be harder to find as time goes on with companies like Best Buy stating that they'll no longer be selling them.
