Currently not, because it's not de-facto decentralized. There would need to be multiple relays, managed by different organizations, AND multiple app views, also managed by different orgs, for me to consider it such.
The non-existence of de facto decentralization indicates that the ecosystem doesn't actually promote decentralization, even though it technically allows for it.
I guess it's time to migrate to piefed. I really love some of the things they're doing - but I'll miss lemm.ee, I feel most other instances either defederate way too much, or way too little (as in, not at all)...
