I had to look this up, and the law states that the Sozialauswahl (social selection) only applies to employees who have the same qualifcations, rank etc. The law applies when the company is doing across-the-board layoffs (e.g. because they have become unprofitable).
It says that employees who have been longer at the firm, have disability, need to support family etc. should be let go last, compared to employees who have the same qualifcations, rank etc. So, in theory, what you're saying is wrong – the company would not lose their "10x devs" (whatever that means) because of this law.
Also, OP mentions the law, but does not say that he was affected by it.
