This whole spat just highlights one of those truths that's evident to those in the industry:

There is no such thing as a good idea, only good execution.

Being first doesn't count for anything. Having a vaguely similar name doesn't count for anything. In the end, only how well your product works, how many users you can attract and retain, and how much value it provides matter.

There is such a thing as a good idea, it's just not very defensible, because once it appears to be working well as a business, the copycats come out of the woodwork.
