I believe most people, especially in the SLR community, know that Sony bought over Minolta.
Thing is Sony is known as a premium brand. That's its strength and weakness. The SLR community aren't exactly (no offence please..just an obseration ok...) the lifestyle type of people. They feel that brands like Sony are superficial and overpriced.
I guess it's a bit like apple in a sense. Many people are anti-apple and pro-orange just coz they view apple products as a superficial fad. But, when you really look into apple products, there really are a lot of good things going on for them eh?
Some Apple products are indeed overpriced. You can get the same specs for almost 1/2 the price in some cases.
