> what sort of evasion technique is being used here

Using a user-agent that looks like a desktop user-agent, rather than including the name of the actual project/product that is being used.

I understand why though, plenty of websites block anything that looks like non-desktop/mobile user-agents, so makes sense. Besides the pragmatic reason, I also agree with menacingly that it doesn't matter, people should be able to use whatever user-agent they want to access the content you've put publicly on the internet.
