Perspective from my side of small automation business ownership We started cleaning out company dependents dev stack from not necessary components starting mid last year. This activity just picked up full steam and we're planning block stuff like .microsoft.com and .GitHub.com in our main mikrotik router next month. My engineering team did amazing work divesting our development stack from windows. It is very hard to achieve in automation business. Most software development packaged for windows only. They did so much work replaced hardware vendors who did not work with Linux. Some work good with wine and we keeping them. We have internal company's gitea. We mirror EVERYTHING from GitHub we need internally. Even debian repositories! I expect that we can soon operate without internet connection for core business (install software on company PCs, develop automation code, etc), Company trucks all have 4TB hard drives with everything necessary for work outside the office. We have email and calendar on proton. Highly recommend amazing service and support. US companies cannot keep my company hostage anymore. It is hard to achieve this. But you can do it. Even we did in the field where windows OS is king.
