To put an example to the other comments, look up the history of the XYZ domain - in a nutshell, they had a fire sale selling domains for pennies to gain market share. Besides normal people, three groups descended upon it: spammers, squatters and hackers. 6 years later and the entire .xyz space is blocked in Enterprise firewalls (source: my workplace) due to that behaviour, preventing me from getting to valid tech sites on the TLD. The XYZ image is still tarnished from cheap domain fire sales at the beginning of it's life - I'd never pay $50 for anything in .xyz today.
To contrast, the .io space entered at what, $50 USD? and continues to be expensive to maintain year over year, providing a natural monetary resistance barrier to the same three groups of people (spammers, squatters and hackers) and seems to enjoy a healthy respect amongst internet users; most consider it a tech-type domain space with tech worker dollars buying the domains for real sites, I even owned one for a brief period when they came out.
While I only named .xyz above, my (enterprise) company blocks several other TLDs as well like .info, I'll check .icu when I'm back after holiday but would not doubt it's blocked. Corporate IT subscribes to some sort of hosted service, I would not doubt other companies are using this same service (name-brand).
I think it's just part of some generic category of strict blocking used by the hosted service - there's a lot of other stuff blocked, we generally don't get reasons as users other than it being the corporate security posture. We are a business partner of many firms (some have high security due to their needs) so our company trends in that direction - maintaining compliance is a big deal, entire team(s) manage it at various levels.
Do you know the name of the service? Blocking .xyz names as a whole would cut your company's employees off from accessing sites like Engine.xyz, ABC.xyz, and Starship.xyz.

I don't know which point you were trying to make, but as far as I could tell that's the business model that's being followed by all vanity gTLDs.
The only nuance I've noticed is that there are a bunch of domains being sold for peanuts with the caveat that after a year or two it's price is hiked to somewhere in the range of 30-50$.
