note that i am referring to USian federal (public domain) versus other local government entities, not to commercial interests which i assume to be protected by default.
also note that copyright issues are taken more seriously by default in certain other countries due to a higher osm participation, that probably get overlooked here for now, together with the prevalence of public domain data that simply does not exist in most countries.
however as i see osm participation in the us of a increasing and a higher awareness of data quality, for which all participants should be proud, as well as increasing use of osm by third parties, i would imagine an increase in awareness of these sorts of issues will follow, with more pro-active action than reactive deletions.
i do intend to reply in the area of your shopping mall with further commentary there on this issue, assuming that does not fall from my radar between the time i have a real life(tm) (kezboard driver is in a weird state giving all-caps, inverting the shift key, or all lowercase with no chance to uppercase letters, apologies) and when i have a short time to catch up on my osm community service of ten hours daily that has accumulated into many non-stop days backlog.
i don't think you will be encountering bayernatlas, swisstopo, or even Maps4BW (can you guess the legality of that last one?) in the areas you are active.  however, do note the difference between google maps as source (taboo) and google search (a grey area).  where you ignore notes commentary referring to google maps, when i see the same, i explain how that source is not allowed and close the note with extreme prejudice.
if i had snapshots of g-maps from the time i got started in osm, i could show how many businesses were marked in the former in totally wrong locations, leading me to wonder if the tiny community had additional branches.  by now i suspect google has most of those corrected, but i have not bothered to look in years.
but i am digressing.  note that for a google text search with lynx browser, i see little more than links to other sites, no maps, no business listings.  this may well be different with other browsers.  still when google algorithms like fuzzy matching come into play, like trying to decide if a vague note with typos is of interest to osm, i try to make that clear in my commentary and myself consider that info tainted/must-be-credited/-documented and do not act on that info, leaving it to a local to discover the ground-truth.
the same would hold true for any other search engine, bing, altavista, gopher, or whatever.
.
note that in the eu, there is a now-tabled (i know tabled has several very different dialect meanings, think postponed) requirement to implement an upload copyright filter that would negatively impact osm, with both osm and google maps attempting to document reality, thus, assuming good failth (what does that typo say about my mental state?) naturally leads to conflicts.
but we have long since derailed the original commentary.  don't overthink copyright, as it seems you may be in the mental state i find myself without sleep and disconnected from reality and obsessing about details, when a couple days later after recovering i look back at what i was doing and wonder what possessed me.
