I would hate to live in the world you imagine where every single awful thing that isn't obviously illegal is considered acceptable by society.
I don't like the colour of your shirt, so I'm going to say it's objectionable. It doesn't break any laws or infringe any regulations, but I want a judge's opinion on it anyway.
See?
In the case of passing off a service you offer as begin the service of another company, there is a clear legal case to answer. And as I recall this is settled caselaw in the UK and the people pretending to be other companies are in the wrong.
It wastes the time of the defendant and the legal service, which harms society.
It imagine it's also super stressful and expensive for the defendant to go through, even when it's thrown out.
Consider: - Cutting your grass at 8am when your neighbour works nights.
- A well off person putting their child up for adoption because they don't want the hassle.
- Payday loans given to people you know won't be able to pay them off, ensuring they pay you far more than the value of the loan.
- Banks processing payments out of order to trigger overdraft fees that would otherwise not have been collected.
