People on HN don't typically encourage cluelessness, you really should be careful with what terms you use around here. Language is a powerful tool when used properly if you start using words without knowing their meaning you make a fool out of yourself.
An important part of that definition appears to be:
"using a domain name with bad faith intent to profit from the goodwill of a trademark belonging to someone else"
Looking at the list of domains on that site I can't see any that meet that criteria. If someone wants to speculatively registers domains that don't conflict with existing trademarks or company names I don't see what the problem is.
The interesting bit is that the vast majority of those were registered for projects that never saw the light of day. My priorities have shifted over the years (mostly: kids) so I've decided to slow down considerably. Hence the sell-out, I don't think I'll ever get around to most of these, maybe one or two that I'll put some weight behind but my days of launching 3 different projects per year are with a high degree of certainty behind me.
Just yesterday I wrongly typed musicbrainz.com, looking for the powerful open source music tagger. It appears to be in the list. I don't mind grabbing a few bucks from a big Corp when they forgot to get their domains, but I find it a bit vulturish to squat names of open source projects.
It might be the case that Jacques did register this name without knowing, but it seems not very likely.
There was a rumour that musicbrains was going the route of CDDB (now gracenote) and I registered the domain on the off chance they were going to close the data.
A similar thing happened with freedb (hence freeddb), which ended up powering daz.com for a couple of years but with better replacements out there the project was shut down.
Funny how everybody is always so ready to see malice.
Check out reocities.com for one that did work out as planned (at least, according to me, I'm not sure Yahoo would agree with me there).
Well, if you appreciate the current work of MusicBrainz team but foresee the possibility of them going commercial, maybe you could, meanwhile, link or redirect to their official http://musicbrainz.org/ site. That could be a fair solution for non lucrative project domains.
Let me give you a hand so that in the spirit of the linked article you may educate yourself on the subject:
