Yoi don't get ads if you pay for YouTube, or if you pay enough for most streaming services. Most papers and such offer an ad free subscription tier too. Cancel TV and use YouTube TV if you must.
For Google, there are ad free competitors, or just use ad block.
They'll be around as long as the financial incentives are there. Micropayments failed so many content providers are moving back to pay walls again, whether it's Patreon or adult videos or Steam or whatever. Gotta put food on the table somehow. If you don't want to see ads, just pay for the producers' time some other way.
