There certainly is a stigma in many companies that employees should use their employers products. I used to do work at some major beverage manufacturers, and for example, carrying a can of Coke into a Pepsi office will literally have you escorted out of the building. For lunch, Pepsi employees are heavily discouraged from eating at places that serve Dr Pepper or Coke products. Company money absolutely cannot be spent on buying catering/services from caterers that don't have Pepsi, etc. For airlines, I have a friend that works at United and he has said multiple times about how he hopes his colleagues never find out that he flies American sometimes because it's cheaper when flying to his hometown.

More recently and relatable to this forum, there was a post a week or two ago where a GitLab employee got lambasted by the CEO for using Github for his personal projects rather than GL.

If anything, I think this is an interesting observation that Cloudflare might have 'less of a stick up its butt' in terms of policing what its employees do. Is this thread the right place for that discussion? Idk, but it's an interesting discussion nonetheless.
