Probably not a popular choice, but my VPN comes with an ad blocker which works great.
I'm still using Nord VPN as I got an insane deal a few years ago. Now it has something called Threat Protection which blocks all ads whether on my desktop browsers or on mobile.
✨Edit to add:
Yeah down vote me. Nord was a blackfriday deal from 3 years ago. Much has changed since then.
I travel full time and I'm now in the market for a new VPN provider. I don't have my own router.. I don't even have a home.
Instead of just down voting, perhaps come with some constructive ideas or suggestions, thank you! ✨
In all my travels, in all the cafés, libraries, hotels and co-working spaces I've used around the world, never have I seen anyone pull out their own router.
I'm not dismissing it's potential or usefulness, I just think that for me to avoid adverts and to connect to a few streaming services from weird locations it might be a bit overkill.
