What is the adtech that's leaking through? I regularly use Youtube with uBO Lite, and it does infact consistently prevent me from seeing ads. I've yet to see a single one.
There does seem to be a war going on between Youtube and adblockers where sometimes Youtube will show me a screen saying that adblockers are prohibited instead of playing the video. But usually a full-page reload which I guess refreshes uBO's rules (either the original Full or the new Lite) fixes it. I'm pretty sure this also happened under the original full uBO, so I don't think it's specific to any new limitations of Lite.
There are a lot of different ways to respond to you, since there are so many features that have different effects. But I'll focus on one I care about, related to tracking. UBo can detect cname cloaking, where a provider hosts 3rd party tracking via a CNAME DNS record attached to their domain. UBo can detect this and block it, while the lite version cannot.
If you care only about ads, then you can determine whether the extension is working purely based on your annoyance level while surfing. But I care about tracking as well (CNAME cloaking is one example), as well as the ability to customize the experience (import my own filter lists, for example).
These capabilities aren't present in UBo Lite. So it feels like a real gap to me. For context, I was an avid UMatrix user for a very long time, but Gorhill discontinuing that showed that I was in a tiny minority. Reminds me of when James Gosling told me I was a dying breed because I still used Emacs. If the inventor of the technology doesn't even use it, maybe it's time to move on! =)
