I personally have no problem with paying for a service. However, if I buy premium to remove the ads, YT has no longer the need to collect my data. But it is Google and they won't stop collecting. That, plus the fact that Google basically has a monopoly with youtube are the reasons I don't buy premium.
"Your info won't be used for ads". Does that also mean that they won't collect any info about you? Theoretically, they don't have any reason to collect data anymore because you pay them.
I think this is the general conclusion in the topic that it depends on the situation. Maybe at the moment, emotion will also alter your decision at the moment. I suppose I would indeed never accept service to attack another country, only to defend my own country/land.
