I take it this is a matter of the mods having some access to information that I don't (given that this account is only 2 days old), but:
In this case, I think much of what this user posted sounds pretty reasonable. I'm not a Microsoft fanboy or anything, but all the vitriol Microsoft gets in light of all the love that Apple and Google get seems silly to me.
I think the concerns some people have that Microsoft will quickly return to their old ways are legitimate, but also a little on the paranoid side. That argument is contingent on Microsoft actually regaining their market position that they once had in the 90s and early 00s, which, frankly, I don't think will ever happen: most developers now flat-out expect that their development tools will be Freely-available ("Free as in Freedom", etc.); most end-users now expect that the "apps" they want will be available for free or at least very cheaply (with prices listed in cents rather than dollars) -- I've seen many comments in the Google Play store where users are complaining about the price of a $2 app, forget about $5 completely. Frankly, people simply aren't willing to pay for software anymore. Regardless of how you feel about that, it's obviously the case these days. As such, I don't think it's unfair to claim that "free software has won".
Furthermore, Microsoft seems to be catching a lot of flak for things that Apple and Google do on the regular, yet many are willing to overlook. I recall seeing a recent thread here on HN in which a user pointed out that Google's update practices are the same if not worse than the recent Windows 10 update fiasco. Yet, you don't see nearly as many people complaining about it.
Finally, it should be obvious that any for-profit business exists for the purpose of generating profit. Given that, it should be no wonder that a business's behavior will be driven by a motive of revenue. Especially in the case of publicly-traded companies, there has been a long history of business behavior motivated by shareholders' interests.
All that said, I have to trust that the HN moderators made the right decision here, but I honestly haven't seen this user make any claims in this particular thread that seem unreasonable. Yes, they are defending Microsoft in their comments, but sometimes I feel as though Microsoft actually needs defending in nerd-circles nowadays, simply because their checkered past makes many of us unwilling to accept that Microsoft may have actually made a change of face recently. Furthermore, is a pro-Microsoft shill really any worse than an anti-Microsoft shill? Going yet further, I've seen plenty of HN users who talk like pro-Apple shills, yet it seems that since so many around here agree with them, that's deemed acceptable.
Anyway, I just wanted to put in my 2¢. Thank you for all that you do to keep this place clean, even if I might not always agree on what constitutes cleanliness :)
