1 second google search -> https://www.die-linke.de/partei/programm/ -> Marx's manifesto is cited among the first paragraphs -> the literal first sentence in point 3's second paragraph -> "Our goal of democratic socialism in the 21st century is a society free of domination in which all people can live in dignity." They mention the process of transforming capitalism to state mandated socialism and control of all companies by a democratic process. A democratic socialism is not a social capitalism, they don't support capitalism in any way or form, and they want to actively move away from it, which they also say among the first sentences on this very page.

The crux of it is that they are not anti-democratic.
German law tries to protect against anti-democratic groups and categorizes them as extremists (including left wing extremists) if they a threatening democracy.
In practice that means that group is then surveilled. If there is evidence that the group tries to overthrow democracy, they are banned.
Die Linke is in many ways _more_ democratic than other groups and parties as they support direct democracy and workplace democracy.
> The crux of it is that they are not anti-democratic.
Die Linke tolerates antidemocratic hate groups within their party and is a financial sponsor of others. All of this is common knowledge, all of this can be looked up easily.

I know quite a lot of parties that were never once watched by a government watchdog, nor do they continue to support extremist groups, nor do those other parties continue to attract extremists at their demonstrations, nor do those other democratic parties have a continued problem of antisemitism within their ranks, nor do they have a dark past and continue to employ people at high ranks that were leaders in that past.
It's a little bit harder. The problem is that the SPD will also talk about democratic socialism and does indeed just mean social capitalism with that. And depending on who you talk with at the left, there is still the idea to use the power of capitalism, just to remove the negative aspects with various means.
But indeed, the program now does distance itself from social capitalism specifically and gives further reasoning to why. I wasn't aware they spell it out so clearly now. We can still argue about how much capitalism would be left when following their program - like when the means of production are owned differently, but used similarly - but I have to give you a point there. My comment as written was not correct.
