There's a bit of hypocrisy going on here. When Person X accuses Person Y of being a shill for Company A because Person Y's stated opinion is that Company A's product is better than Company B's product -- this same Person X is being a shill for Company B, albeit indirectly.
Sneaky, isn't it? Not that I believe anyone is being a shill here. I'm just saying, you know --- it's a speck vs. log sort of thing.
