Not really. Ad tier is actually more lucrative for Netflix, even more than their Premium tiers. It's not only the fastest growing tier as everyone wants cheaper tiers but ends up making more money for Netflix. Ads sold at premium to a captured audience.
There's a gap in the Gamepass tiers for $20, and $25 price points. Could be perfectly positioned for Ad supported tiers. I expect Premium to go up to $18 month, eventually $20, and ad supported Premium for $15. And an ad supported Ultimate for $25 month.
