so they are probably losing money by maintaining that option open but they realize that if that option is not present they are going to receive a lot of criticism especially since Microsoft is one of the most recognized companies about technology around the world.
As I pointed out in my previous post, which you ignored for whatever reason, Microsoft doesn't lose anything if people aren't making use of Bitcoin as payment option. Their payment processor charges on a per transaction basis.
Meaning, if people don't end up using Bitcoin as payment option, there are no fees involved at all. It's not a credit card or a banking service where annual or monthly fees get charged.
They just ditched that option because at their level, the revenue it generates is just too insignificant. Even if they aren't losing anything by keeping that payment option active, they want to get rid of it anyway.
But of course, they reverted back after loads of rightfully justified criticism.
