"Never attribute to stupidity that which can be adequately explained by systemic incentives promoting malice."
I'm not sure what makes Google so different that it should be exempt from general trends around reviews. Businesses have their interest aligned here: removing negative reviews and faking positive reviews are beneficial to each individually, and can't be directly weaponized against competition. Google has no strong incentive to keep reviews honest; regular users will not replace Google Maps with OSM over a review issue, while a business might want to stop paying Google if they get bad experience on the marketing front.
Have you actually thought about this at all? Why on earth would ANYONE bother reading reviews that they know to be categorically fraudulent? Without keeping the reviews honest, at least to a degree that the general public considers them honest and legitimate, Google Maps Reviews becomes worthless and a dead product. Fake reviews are a very real threat to their product's value and Google arguably has very good strong incentives to keep reviews honest so people keep using them.
It's because most people don't pay attention and didn't figure out yet that on-line reviews in general are worthless, thoroughly gamed bullshit. Those who did figure it out - they don't stop using Yelp/Glassdoor/Amazon/eBay/Google Maps anyway, because those services still offer enough value to customers compensate for broken reviews.
So if regular users will be there either way, and manipulating reviews - or allowing them to be easily manipulated - increases retention of paying customers (businesses), which way the incentives blow?

Google drops reviews for a few known reasons. When a location gets negative coverage in the news, thousands of negative reviews from people who have never visited the location. Google then drops the reviews since review bombing is not useful.
Who knows why OPs comment was flagged, but its easy to see how this happens without a big conspiracy going on.
It obviously was intentional to lie to the user. We're just discussing the line at which intentional lies for selfish reasons can be called malicious.
Have you considered when the shadow-ban is triggered by an automated moderation system based on heuristics or ML which Google is known to use prolifically across their product range?
They aren't like baby killers or anything, but they are certainly prioritizing their wallet over your consumer good and even safety.
Imagine if HN charged to post and shadow-banned users.
I'd also write it to remove reviews written by a single account if the reviews across diverse products are substantially similar.
Given how well known other unscrupulous review service tactics are (eg, yelp) I doubt this would be the case. It's hard to keep such practices secret when they involve attempting to extract money from a large number of businesses. Plus Google seems to be reasonably honest about labeling (even if very subtly) when things are sponsored ads or not.
I would find it far more likely that this is simply a symptom of something Google is well known for doing: Content moderation through algorithms/ML which mostly works but still messes up a lot. Either the wording of the review hit some metric on its own, or the business already was detected as being review bombed and your review got caught in the cleanup crossfire. Posting it twice probably didn't help, as that would further convince an algorithm it's probably not legitimate.
