Care to elaborate what you mean by this? There's a lot of valid criticism of Mozilla in 2023 but what this article is talking about doesn't seem like it on the surface.
How will Mozilla compete with Meta, Twitter?

Content is complete garbage.
Decentralisation isn't a feature for 99.9% of people.
I don't think it has a chance to ever be as popular as twitter, simply because they don't want to add features to make it addictive.
This is the wrong framing. We should be asking how the Fediverse will compete with mainstream social media. Mozilla is just doing one part of a larger collective project. And so far Fedi has done so pretty well considering the relative amount of manpower behind development. And there's a lot of reasons for that.
