For me its solely because of a ad free experience on my TV, since its the primary device I’m using it on. And i got it relatively cheap from turkey so it’s not that big of a deal. I might reevaluate if the price increases though.

It really boils down to a few reasons:

• I don’t like ads, and I prefer not to see them
• Running a platform like YouTube is not cheap, and I understand that Google needs money to keep things running.
• The revenue of Premium is split between YouTube and the creators, much like ad revenue is. So it also supports the channels that I follow.
