Here's my brief personal take on this issue:
If a vendor spends years being rude and dismissive to people over email, they shouldn't be surprised when those same people stop giving them the benefit of the doubt when discussions come up in public forums. Americans in particular will go out of their way to "hit back" at someone who has been rude to them. That's why well-run American companies will simply never do it.
If you're going to run a company that sells globally, even an earnestly engineering-focused company, you need to be willing to do good customer service and support (including pre-sales support) as an ongoing commitment. Engineering merit is only one of the criteria for success, it doesn't earn the business on its own.
The vendors that are most consistently and vocally supported by individuals here on the forum (and on other platforms) are typically those who have given excellent customer service experiences, not necessarily those with the most extreme or perfect or well-marketed product lines.
