The safty lock issue doesn't bother me since it wasn't added as part of any 'agreement' with the government. Whether it's CYA or just a feature thay they think some people will want, it doesn't really matter. It still has the best price/performance ratio out there and they can remove the lock from the design any time they want.
I don't see the lock as 'caving in' since, as far as I know, they never signed an agreement with anyone. I didn't notice a price jump when they added the lock and the lock doesn't get in the way, so what's the problem?
