MacUpdate has been THE place to check, download, and even discuss Mac software and new versions for many years (has been around since 1996). I have always favoured developers' original websites for downloading and buying software, which MacUpdate gladly redirected to, and use MAS only if I have no other choice. But if there is a choice between buying a non-MAS version and MAS version of an application I will ALWAYS select the first. For too many reasons.
Nevertheless, Mac users were spoiled believing that they would never regress to the lame download websites Windows always had. But some saw that coming. And it is a recent trend on the industry as well. If it was money they needed they could ask the community, their user=customer base. At least they could be open about it.
It appears that they have erased the reporting comments in their Skype thread/review, which is even more lame. Looks like they are greedy. If this is the case, please spread the word here and everywhere else. People should know.
