"Slander" entails making false statements, whereas this was just a statement of fact, free even of condemnation. People who read it make their own value judgments.
No, sorry, false. A sentence of the form, "which is why <person> does <thing>", i.e. "<person I never met> did <thing> because <reason I impute>" is never, ever a statement of fact. It is _always_ an opinion and an attempt at mindreading. And in this case, it's ill-informed. As lend0000 has repeatedly told you, firms like these are not exposed long to the market. Hence, "likely ideologically motivated", unlikely a nefarious ploy, but again this is speculation.
