One could splice ads out of the video on the client just as easily as they splice them in, assuming you can detect them (which could be done via crowdsourced databases a la sponsorblock).
Sure, and I can use "technology" to identify those splices, and fix them in various ways that work for me because I control the client (unlike Chrome users) and that gives me the power to make the web behave how I want it to, if I'm willing to put in the effort (or someone else does it for me.)
