Marko - from a different cultural perspective, as an Australian, you don't want to know what we call everyone else. Especially our mates.
But I didn't take Bapu's comment to be particularly snarky, to be honest. I'm in the same boat as he is, wondering why this is a thing. Cakewalk has embraced a new model where you can pay year by year, like we've always done in the past, or month by month (and better yet, you own that 12 months worth of updates, unlike what other companies *cough*Adobe*ahem* do), and now for a couple of months, to say thanks to the user base for being loyal, they're giving us a chance for Platinum users to get lifetime updates.
I can't see how this is a bad thing. Artist and Professional users aren't getting this deal, Platinum users won't get it after the deal ends (unless they do specials again - who knows?), and you don't need to take advantage of it anyway if it makes you feel uneasy. Perhaps think of it as a "buy one get one free" or "MEGA SUPER SALE THIS FRIDAY ONLY!!!" kind of sale if you like. Get yourself a big TV for $200 tomorrow, it's back to $1000 the next day.
In this case, I think it's more of a push to reward a bit of brand loyalty, to be honest. If you feel you're part of "the team" you're going to be more into using the product, telling other people about it, and generally helping make it better with suggestions and bug reports.
And if you want to be really cynical about it, you've got a program you've paid for that lasts "forever" (whatever that means in the software world)... you're gonna want to keep using it, right? And since it's your DAW of choice, you'll be more inclined to buy additional stuff that works with it - Pro Channel modules, plugins locked to SONAR, etc. and you'd be involved in all of the PR material that shows new products, without the need for being spammed because you're part of the community, because you want to be a part of it. It's great marketing sense if nothing else.
I've been hanging around the Cakewalk community since the mid 90s, back when they were om Usenet newsgroups even. The one thing that has made me stick around more than anything else is the people in the company. They are genuinely good folks that just want to make a good product. They don't always get it right (you don't wanna know my list of gripes that I want fixed! It even scares me

) but at no stage have I ever felt that we were getting led down the path for the sake of dollars, and that feels especially true in the last couple of years.
TL;DR version: relax.
