A little more than a year ago, people in uniform came to check the software license. The panic after leaving and the promise to “come back and check” made our would-be admins quickly move to free alternatives.
Communication with the main popular software catalogs in which there were about 10 thousand "free" programs was horrified - a lot of school handicrafts, adware, trials and junk programs in general, in which it was impossible to find anything valuable, were forced to raise their "catalog" .
Naturally, in order not to turn into another “garbage” on the publications, pre-moderation and evaluation of the utility of the software from the point of view of the administration is superimposed :)
