Microsoft is effectively a monopoly, to say it's anything else and that other browsers are available is a nonsense for reasons that everyone knows.

Appealing to reason is a waste of time as no big monopolistic corporation will willingly forfeit money. The only realistic (effective) solution is legislative. I don't see that happening anytime soon in the US but perhaps it's possible in other jurisdictions (more likely now that the US is no longer the flavor of the month with many).

the other "realistic" solution is to use another o/s.
