I think the bottom line is these companies want you to buy the new product. Somewhere along the line they loose sight of support since it doesn't generate income. I say "these companies" because there are quite a few out there pushing new hardware constantly. They base their survival on new product revenue. If you happen to be Gibson you sell a product that is timeless and doesn't necessarily need a huge revision to keep going.
Look at Nord...they keep a fairly consistent well made product on the market. Yes they make changes, but not often and not radical. They make a great product.
I was drooling over the 88 key controller from NI, but decided to wait given their history...great software, iffy hardware support.
I've received great support from Presonus on the hardware end of things, my needs have been fairly simple though. Luckily I never had software issues with them. Not sure, could have been banned for promoting Sonar over there? We seem a bit more liberal over here since we have a few regular Studio One users who still come over and still use Sonar and they say what they like and what they don't like. If it was habitual and considered an attack of some kind, then I'm sure one of the mods would take action on that. Sorry to hear about that.
We have one or two who were banned from here and went over there. One of them was great entertainment and I hated to see him go :)
