Namecoin failed because of distribution issues, among other reasons: https://www.cs.princeton.edu/~arvindn/publications/namespaces.pdf

This "spaces" scam is by NOT what bitdns did. I am old enough to know and tested the defunct Namecoin NMC that was a good intention of decentralizing DNS.

But these "spaces" are just another scam. Don't let them fool you.
They even used a catchy title for this post, showing the level of scam they are willing to do.
You have been warned.

Spaces uses approx. 60 bytes, very minimal on chain footprint. Compatible with core, knots, bip110, etc. Very tiny without any changes needed to Bitcoin.

Satoshi would approve!

The networks need to have separate fates.  BitDNS users might be completely liberal about adding any large data features since relatively few domain registrars are needed, while Bitcoin users might get increasingly tyrannical about limiting the size of the chain so it's easy for lots of users and small devices.
