I'm just tired. On the last post about having Linux at our work, many people that seems to be an IT worker said there have been several issues with Linux that was not easy to manipulate or control like they do with Windows, but I think they just are lazy to find out ways to provide this support. Because Google forces all their workers to use Linux, and they have pretty much control on their OS as any other Windows system.
Linux is a valid system that can be used for work, just as many other companies do.
So my point is, the excuse of "Linux is not ready for workplaces" could be just a lack of knowledge of the IT team and/or a lack of intention to provide to developers the right tools to work.
Linux is ready for workplaces and has been for a very very long time. That is irrelevant if workplace IT support is not ready for Linux and has no budget or time to get ready for it. All your points are meaningless and have never been the problem. The problem is with management, policies and getting in house support for things and all the work involved in that. Depending on the size of the company it can take a lot of time effort and money to retrain IT staff to support Linux. And IT staff are already overworked, under-budgeted and don't always have the time to support extra things.
