This is great, my annoyance with ads is their time-wasting nature. Skipping ads entirely isn't purely ethical, but this seems like a better compromise for both parties. We want to use YouTube free of charge and will see the ads in a short manner that satisfies YouTube (I hope).
Something can be both unethical and commonly done. In fact, some quite seriously unethical things were commonplace for centuries and others are commonplace now even though most consider them unethical at heart. Skipping ads needs to be ethical or unethical because it is, that it is done is irrelevant.
It absolutely is. Nobody is obligated to look at this crap.
Their entire business model is based on sending people free stuff loaded with ads. They assume people are going to look at the ads. They only have themselves to blame if their assumptions don't hold.
