This statement indicates that what is technology is decided by popular opinion, not by any inherent meaning in words. Certainly the meaning of words change with time and they have no inherent meaning, so in a very real sense, definitions are decided by popular vote. However, if Twitter is a tech company, then so is every newspaper, magazine, bank, credit card company, any business with a data base for inventory management. It’s a useless definition. Let’s go with the actual mainstream definition of a tech company, a company that develops, produces, licenses or sells technology or technology services, and Twitter doesn’t do any of that. It sells ad space and subscriptions, the business model of a media company.
