I'd treat this about the same as datasheets for mechanical or electrical parts.
When I buy an electronic component as a regular consumer I expect the datasheet "typical" values to be accurate 90% of the time. I can imagine larger industrial customers would really raise a stink if it's worse than that. However, any critical components in my circuit must be verified and "binned", and that's on me.
Would it be the same idea as an x ray of a critically welded part?
This is the thing. Yes, the marketing material is bad. But, no one in lab trusts an antibody just because of where you bought it. A new antibody always gets tested and validated before use.
That is to say, this looks bad for Thermo Fisher. But, that’s as far as the damage should go.
