Probably.
I was once called in as a consultant to sit-in on a meeting between Hyperoptic reps and a bunch of building owners they were trying to "sell" to.
It was clear the Hyperoptic guys had a well-rehearsed pitch which was fine tuned to their target audience (i.e. non-techie building management committees).
They had well rehearsed answers to the predictable questions thrown up by building management.
However they struggled with or rather tried to bluff and bluster they way out of technical questions.
For example, when I asked them how they could justify using CAT5e for the "last-mile" (i.e. basement area to residents flats), because for those residents on the upper floors this would easily exceed the CAT5e standards limits. (Their proposal was all their active kit was to be in the basement, so no fibre trunks between switches or anything like that).
So you can appreciate why I'm not a fan of the way these companies tend to operate.
Experience round some of my friends in their catchment area was their reps will attempt endless rounds of doorstop selling, on top of that they will then bombard you with marketing letters (which are carefully addressed "To the occupier" so as to avoid being caught by anti-junk legislation). I've seen the junk, and I've been round people's houses when the greasy sales reps have knocked on the door touting their wares.
If you call them or write to them to ask them to stop, they ignore it and continue.
That alone would put me off Community Fibre for life. I have a policy of not dealing with spammers.
I would also encourage people to read the small print.
