If you have lazy devs, sometimes you need to convince (or coerce, or force) them to get them out of their comfort zone and try something new. But typically this is done because management wants more while giving nothing in return which is why no one tolerates these suggestions.

The other reason, which has been used to prevent devs from fixing bad code, is that making money is more important and sometimes that means moving away from costlier tools, or choosing tools because of specific business arrangements.
