I think some people have forgotten some of the comments made earlier in the thread.
First, the minimum price change for plugins is not to make extra money for HS. It is to provide extra margin to allow other distributors (think Automated Outlet or Worthington) to also sell the plugins. Yes, HS will make some extra money on the plugins sold through the updater, but that is a side benefit. Rich & Rick are a bunch of upstanding people, and I don't think they would bother to lie to us about this.
Second, very few (if any) software developers provide unlimited free upgrades. Most provide unlimited "dot" upgrades (1.1, 1.2, 1.3, etc), but charge for major releases. As pointed out, many of us picked up HS for $39 ages ago, back when HSTech was called Keeware Software. In the several years since then, how many upgrades has HS charged for? Zero, zip, nada, none, etc. There are several of these releases that HS could have called "new" and charged an upgrade fee, but they didn't. Unlike (pet peeve) Intuit, that changes the look of the Quicken interface every year, and calls it a "new" version. (and yes before you ask, I would still be using Quicken 99 if my bank didn't provide free copies of the latest version). I don't think that anybody would dispute that Hs 2.0 qualifies as a "new" release. The $40/50 upgrade fee is fair and reasonable. If you don't want to pay it, or don't see any need to upgrade, then don't.
Do I fully agree with all these changes? No! I also want to see what will happen to those plugins that cannot justify a $29.95 price. And yes, I'm not sure I would pay $200 for HS if I was starting the hobby today. But give credit to HS when credit is due.
