I think the dismay is about trying to use copyright to slither around the expiration of a patent, if that is what is going on.
I like the Brompton and tried one in a shop, but decided I couldn't see springing $1400+ for one unless I was sure I would use it a lot, so I would possibly start with a lower cost folding bike and see how I liked it. That was pre-pandemic so I put the whole thing aside.
I'm not concerned about travelling with the bike. The attraction of a folder to me is just an easier time getting it in and out of an apartment for commuting purposes.
