This is a gross misunderstanding of everything in the industry.
Maya is far, far from being on life support. There are hundreds of studios around the world that use it, and autodesk do substantial development in Maya till date including updated adding USD, Bifrost and parallel graph evaluation.
The fact that Pixar have their own animation package (Presto) has nothing to do with Maya whatsoever.
The first ancestor to Presto effectively predates Maya. They've developed a lot of custom tooling and workflows around it for animation. They still use Maya for many aspects outside animation like modelling etc...
Similarly DreamWorks and rhythm and hues also had their own proprietary animation software (premo and voodoo) for similar reasons but still use Maya for other purposes.
Autodesk laid off the entire R&D staff of Maya (outside of Bifrost, which was an acquisition a few years ago and is now a one person show, mainly) and transferred ownership to their maintenance engineering division, if that isn’t life support I don’t know what is.
I think saying it's far from being on life support is really pushing it...
Maya's USD support so far is effectively just Animal Logic's open source stuff bundled with Maya, Bifrost is indeed the one place they're actually still doing development (as they still have that R&D team), Parallel graph evaluation in 2019 and 2020 are really just riding the coattails of work they did a few years ago.
Improvements to rendering infrastructure (Arnold) are orthogonal as far as I'm concerned as it's done by the SolidAngle team they acquired a few year ago.
They're effective keeping it running (moving to newer Qt versions and the future Python 3 version for VFX platforms in line with other DCCs) as far as many people are concerned, which at a stretch could be construed as "on life support".
