Of these: 1, 3, 4, 6, 11, and 14 are the sort of things that might work fine for one DM but not another. 2 and 14 are perhaps left for the DM to flesh out or not, as desired, perhaps keeping in mind that some DMs will be trying to run this using a completely different backstory bespoke to their own campaigns. And 5 is just typical of marketing campaigns everywhere, nothing to see here.
As noted by others, we've done 10 to death. 8 has been a problem with some WotC adventures for a while now.
BUT: 7, 9, 12, 13 and 15 are the sort of errors* that just shouldn't exist (but all too often do) in a professional publication; and the reviewer is quite right in calling them out harshly. 12 in particular has been a gripe of mine ever since they started including battlemaps: they always show things the characters can't yet see or know about when arriving at the map's edge.
* - it's probably worth noting that if a reviewer could spot these things on a read-through that means they weren't really all that that hard to notice; so how on earth did the editor(s)/proofreader(s) miss them? Makes me wonder what other less-obvious issues might rear their heads on a full play-through?
