I think that's being really nitpicky. None of the other firms given as examples are in any way tech firms. Celestica is mentioned in a single sentence as part of a list of firms. The overall theme of companies outside the software industry creating software and marketing it is pretty clearly communicated and unambiguous.
I have seen egregious uses of the term 'tech' used to just mean specifically silicon valley internet software, but this case is more a marginal oversight of one example in passing, rather than a deliberate or misleading misuse.
