In the UK it’s common for supermarkets to advertise “we price match Aldi”. (Aldi is the trademarked name of a low price supermarket chain). Maybe the US trademark law is different, but I’d be surprised if you can’t claim to be someone’s competitor.

It also occurs that even if their were laws in the US that said that you couldn’t advertise that you were a competitor of a trademark, they’d probably be unconstitutional.

1. There is zero reason for this to be an online, cloud-hosted application. This is... a database. 20 years ago, this would have been a 400KB EXE you ran on your computer and that was that.

2. I hope people are not deleting their own logs after uploading them to this service. Surely, users aren't relying on this site as some kind of backup for their data. Especially when their business model appears to be clearly HostageWare.

EDIT-ALSO:

The legal basis for this threat doesn't make much sense. The company is saying that mere mentioning of their company (or product) name "uses the [product] name and brand as a commercial hook to drive traffic and adoption of your unfairly competing tools."

If this was enforceable, how would any project that provides open source compatibility with some company's proprietary format be legal? If I write a program that downloaded fitness data from my Garmin smartwatch and mentioned "compatible with Garmin smartwatches" on the project's GitHub, am I suddenly infringing their trademark? (Not looking for legal advice, just confirmation that this company's position is legally bizarre.)
