Because Mozilla is wasting money on something other than their core product, once again.

Thunderbird is under MZLA Technologies Corporation, their money and resources are unrelated to Mozilla Corporation, who pays money for their Firefox.

I’m not sure if it’s fair to describe a "wholly owned subsidiary" as unrelated.

> Thunderbolt is funded through a dedicated investment from Mozilla and is being developed by a separate team focused on enterprise AI products, distinct from Thunderbird’s donation-supported consumer product work.

Emphasis mine.

		Yes, it's unrelated. Each one has its own resources and roadmaps. They are totally not dependent on each other. Thunderbird and its roadmaps/projects are not affected by Firefox' earnings at all. One's development doesn't affect the others.
