Long term financial interests, mostly. I know the ads run on my network will never, under any circumstance, be allowed to appear without a skip button within 5 seconds. Immediately, if possible. The only conditional is when the skip button appears, not if. And that's divorced from the copy; the component that plays the ad doesn't care what copy is running, it controls the skipability.

If an advertiser does not like those terms and is willing to forgo my users for that position, more power to them. I have every confidence that I will still find advertisers and, in my experience, they will be higher quality advertisers for the demographics of my users. Artists tend to advertise in cheap space that they know other artists will be viewing. You get the idea.

What has me curious is why you see those two as conflicting viewpoints? I didn't need a government to regulate me. Just common sense and care for my users. I'm not going to subject them to noisy or obnoxious ads, nor am I going to subject them to content that may not be suitable for everyone, and so I'm also not going to subject them to overly long ads. It seems, to me, that you have a profound lack of faith in the platforms you use. Which I can understand as a practical realization about the current apex platforms. But I don't know why it would blind you to the possibility of reasonable people acting reasonably.
