How is this different than paying Spotify for the ads to go away? People don't seem to mind that.

Solitaire added ads to something that was previously free and ad free and added ads.

Spotify took something that previously cost money and made it free with ads.

There's also the fact that people can view Spotify as a ongoing service easily while people view MS solitaire as a component of a product. Normal people dislike when you turn their products into services needing ongoing payments

If you read the article:

"A one month upgrade will run users $1.49, while a year-long upgrade costs $9.99."

I'm personally used to pay only one time for a game (except perhaps for MMOGs, where a subscription really makes sense).
