In practice, you don't have money for those, and your team is lazy and doesn't really want to learn that new cool tech, just let them do their job.

In practise, you want to cheap out on paying for training, have your team do their job and learn an entirely new system to expert level at the same time, the "cool new tech" isn't and your team knows that you're trying to sell it as "cool" to pull a fast one on them because you think they're idiot children, and you won't even commit to using it for long enough to make it worth the bother of trying to learn before changing your mind or prioritising something else, and you're humming and hawing about investing in the tools to make the new tech work well because it's free software so why should it cost you any money?

Besides, you won't prioritise maintenance or design, so the codebase is a mess and people are incentivised towards panic-of-the-day fixes and don't-ever-ever-break-anything conservatism - their fault not yours, obviously, it can't be your fault, you don't even work with the tech (you just choose it by fiat).
