Possible corrosion issues aside, does the article have any negative implications for the much sought-for development of molten-salt thorium reactors?

This.

India and China need thorium power. It is non-proliferation fuel and is abundant in these two countries.

It could be the biggest factor bringing down pollution in the world's two fastest growing economies with massive demand for power.

It doesn't really have negative implications for MSRs in general. It's just one design out of many.

The debunked claim is just that they could get uranium fuel utilization comparable to a fast reactor, using a reactor operating mainly in the thermal spectrum. None of the other projects make that claim; either they actually are fast reactors (Moltex, Terrapower), they claim much lower fuel utilization (Terrestrial Energy), or they plan to run on thorium.

Your zeroth-order mental model of a Thorium reactor should be "exactly like a Uranium reactor". It's a different radioisotope; it ain't magic.
Your first-order mental model should be that (1) thorium requires breeding and that works in a thermal spectrum, (2) uranium doesn't require breeding if you're content with fissioning U235, and (3) you can have a breeding uranium reactor but that requires a fast spectrum.
