In 19 years I have never been burned by Valve, in the same period I have lost access to software (and hardware) from Microsoft, Sony, Nintendo and Epic. They are a money making business and will always act in their own interest but so far it seems like their own interests includes not stomping on customers (in my experience).
If no one has ever told them that some bats carry rabies how would they know to Google anything when they find a bat in the house? It’s not something that is taught in school and I’ve never seen or heard a PSA talking about it in Ontario.
