Why games try to support as many payment methods as possible meanwhile a lot of other services offer only card or paypal - e.g HBO's Streaming

In video games people without cards can pay with premium sms or even paysafe cards (they're really handy)

Shouldn't every service try to cover as many reasonable as payment methods? aren't they losing customers?

Is this because they want to force you to sub & forget as hard as they can?

I don't like that because I cannot purchase services "anonymously" and I don't trust some services to give them my card details
