ok, this now somewhat helps to explain why a street in my neighborhood vanished even though both the old inspector and the cleanmap showed it as OK, but it still leaves me with a few open questions:
I can't say what cleanmap does but the old license view in OSM differed from what the bot actually did in at least two important points:
1. The bot used a "blacklist" of changesets, changesets that were nominally done by agreers but in which they used unacceptable sources (mostly, the so-called "copy&paste remapping"). OSMI did not use these lists, so if someone "whitewashed" data by copy&pasting then it would have been shown ok on OSMI but later caught by the bot.
(I assume that not all cases of whitewashing will have been caught, and we will have to use the bot a couple more times in the future to get rid of whitewashed data when it is discovered.)
2. The bot knows about "knock-on effects", where a way is deleted if all, or all but one, of its nodes have to be deleted. This is something where OSMI would have marked the nodes red but treated the way as if it was safe.
