Is domestic software as bad as it is described in the comments?

I took part in a discussion of domestic software offered to replace imported software, and was not satisfied. I won't hide the fact that I went there to get specifics, but there are no specifics – there are just words about domestic software being bad, but there are no indications of why exactly it is bad.

Well, if that's the case, then I'll have to deal with the issue of specific shortcomings of domestic software myself. As you may have noticed from my articles, I'm stubborn enough to bother checking what others casually throw out unconfirmed statements about.

BACKGROUND: I remember stories about how some program is bad, but upon closer inspection it turned out that the problem was not in the functionality, but in a familiar button. Well, like, a person learned some button in the software he uses and not seeing this button in other software, he concludes that the other software is bad. And there the button/command/option/… may just be called differently, but the functionality itself is there. I remember fans of some browser, thinking that only it has some very necessary functionality. I remember fans of a graphical raster editor, I remember fans of a text editor, I remember fans of an operating system, I remember fans of online services, etc.

Therefore, when I am told that some domestic software does not have some obvious, generally accepted and very necessary functionality, a natural doubt arises in me. On the other hand, anything can happen in life, and therefore I have an offer for you.

Let's take, for example, SMath, which appears in import substitution lists as a domestic analogue of MathCAD.

And write in the comments what typical and necessary functionality is missing in SMath, without which you cannot switch from MathCAD to SMath.

Or some non-typical functionality, but very necessary in your subject area.

Of course, like comments that describe an objective problem and dislike where the problem is imaginary (the functionality is there, the functionality is not really needed, etc.)

And then I’ll take this list and ask the authors of the program whether the real problems are described or if the button is simply called incorrectly.

Seriously, I'll just go ahead and ask. I can do it. I'll do it.

P.S. If it works out well and the list of problems is meaningful, then maybe we'll try poking a stick at some other “domestic analogue”.
