I’d probably just pick a better analogy. If the job can be done on the operating system provided, then it can be done equally well by anybody using that operating system. No need to grow bigger hands.
If you’re working from the premise that your brain is only suited to work with one operating system, then you’re really only harming yourself, by shutting down any opportunities you may otherwise have open to you.
Small organisations have the luxury of letting people choose their tools more freely. As they grow, they tend to have to restrict this more. Not just because they might have to support the tools you choose to use, but because they absolutely will have to support how your choices work with all the other tools they have in the organisation. At scale, this starts to get out of hand pretty quickly, and the only way you can provide a good working experience is by adding constraints to the tools used.
On top of that, some organisations have regulations and compliance requirements to meet that make it even harder. If your basic procurement pipeline includes $10,000 of vendor due diligence, then you don’t want to just give everybody free reign to use anything they feel like. If those choices introduce additional ongoing compliance costs, then you want to control that even more so.
You could ignore all of that, and focus only on how it affects you. But there’s good reasons that organisations do that sort of thing.
