They have a business deal with Microsoft, they have no business deals with Anthropic or OpenAI. Employees were using their private subscriptions for work related tasks. I guess a strongly worded letter to the employees was not enough.

Probably for the same reason as in most companies: Microsoft “assured” them that their data is safe… who cares about the Cloud Act, right?

Or: Microsoft has the data already, so why give the data to Anthropic and OpenAI, too?

Microsoft will helpfully house that data in China. The others won't.

AWS and GCP also use local Chinese joint-venture partners to comply with Chinese regulations. Warm greetings to Moscow!

I rather trust MS than OpenAI or Antrophic

MS don't train your data

MS barely trains on their own data given how shit copilot is even when dealing with MS stuff

That is one of the best assurances that we have these days, that is how bad is the situation.

I second this.

Same reason why the Fortune 200 company I'm currently doing some work for uses it. 70% discount on api costs compared with Anthropic, but access to the same Anthropic models.

Here every person gets $500 of copilot "credits" per month and that is a lot of use. $500 in Anthropic API gets used in 3 days.

The only disadvantage is that copilot cli has a very crappy and limited plugin system. For example a plugin can register a hook when a model calls a tool, but it's impossible to show a question to a user from such plugin.

Also it's "Autopilot" mode is designed to waste tokens. It injects things like "did you do absolutely everything you can about this? If not continue" and it's impossible to disable this without reverse engineering.

I dont think opting for copilot on a cost basis fit into "ban".

Because nobody was ever fired from choosing Microsoft, and apparently this still holds for AI?
