I think it's really cool that Maps has these community features (and they're often more up to date than even OpenStreetMap).
But the process is totally opaque. Sometimes you submit a random edit[1] and it shows up a minute later. Other times you can submit the same highly important edit (this road will be closed for months), multiple times, and it won't show up for months if ever. But beyond the initial confirmation that says thanks, they'll review it, nothing. No status updates unless it actually goes through. No request for additional evidence or denial with or without reason. Just silence a lot of times.
I wish they'd provide followups and really allow the local guide community -- their volunteer boots on the ground "ground truth" team -- more transparency and proper change tracking. We want to help. We live in these places and use Maps multiple times a day.
Maps's errors range from inconvenient to outright dangerous (my area has a bunch of fake stop signs that don't actually exist, and real stop signs that aren't on Maps, and I've nearly slammed on the brakes when it told me there's a stop sign when there isn't). And it's gotten a lot worse recently. Not sure if they're using more AI or whatever, but there's just wrong information everywhere, often for months if not years. I fix them every time I can, but the process is aggravatingly slow and seemingly random. It would be better to use peer local moderators instead of whatever invisible process they have now.
They don't lack data. Even the article says they received reports. They lack a functional pipeline to vet and approve that data in a reasonably timely fashion.

[1] Side anecdote: One time, deep in my discontent during an election cycle, I marked a local political headquarter of one of the two major parties as a "Garbage Dump". It went through immediately and stayed for months, even making the local news. Every time you were in that area, the icon would prominently show up. Yep, political party X, still ever the dumpster fire. Got a kick outta that, heh. Sweet, petty digital vengeance.
