Its brave of you to assume that giving them more money results in consistent updates.

Wow players getting patches cut and content simplified despite shadowlands apparently being the best selling game all time when it was released.

I think Diablo Immortal has had an update since release, but theres no info on the Blizzard news site about the game since July 19th

Heroes of the Storm had similar sorts of monetization and literally was just cut off from future development like a year ago.

I can see Overwatch having updates for the first 3 months consistently, but if its not extremely popular we will see less and less just like Overwatch 1, yet the new Live Service stuff will all be there.
