How not to become dependent on developers with the author's CMS?

Question

CMS

It actually happened that they recommend CMS of their own design (convenient, intuitive, integrated with 1C).
We don't want to depend on developers. We are trying to minimize the risks and not be captured.
The developers refer to the universality of the CMS, they say the code is open and by hiring any more or less qualified programmer, we will be able to resolve issues on the site on our own.
Hmm ... can this be?
There is an opinion that programmers do not take someone else's, unknown for any $.
Question. Is it worth getting hooked on such a CMS? It costs 40,000 rubles.

Answer 1

The code is open, but they sell it?
Well, in general, you can’t immediately say what to do here, but if you are confident in the qualifications of the developers who created this CMS, then why not.
For example, it would not be difficult for me to maintain well-written code, and not pasta.

Answer 2

From my own experience - if a company has its own CMS, and it sells for 40,000 - most likely it is a quite successful company that will continue to develop and maintain its CMS. With equal success, you can "get hooked" on any other CMS, and you will need a support and development specialist. And here the development company will be preferable - most likely, your specialist will be trained there and will answer stupid questions. And in the open source communities they will send you to read Google, as usual.

Answer 3

just look for a programmer and not for money, but for the idea of
​​​​making sites on free CMS sooner or later you will get

Answer 4

If this is an opensource project with documentation, readable code, intelligible comments and some kind of community, then no dependence threatens. And if this is self-made software, the source codes of which are not sought to be classified, then spaghetti code, lack of documentation, and, what the hell, obfuscation in various forms will interfere with support. Of course, this is not worth taking on - although some are taken, they can just ask for good money.

Answer 5

just the same well-written code, not pasta + normal documentation - in open common CMS.
