Not gonna lie, I never even noticed there were ads. They all seem to be links to other Addons by that creator.

If all ads were that unobtrusive and related to the content I probably wouldn’t even feel the need to use an ad blocker.

It’s not like this is unheard of for Addon creators anyway. A link to the website, or a “See our other projects” link is perfectly normal for Addons/open source software. I think you’re blowing this out of proportion.

Those are all things made by the same dev, no? Why would you have a problem with the dev of something you like pointing out their other works?

Those look like links to the devs other add-ons? Not really ads.

Are you that averse to ads that devs can't even promote their other work lol?

Which one is it?

Use Chameleon

I honestly have never seen that, does it come back after clicking it away? Also, probably because it's just good otherwise.
