I read the article you linked but I don't see how it backs your argument that degrowth could be compatible with some form of capitalism (as you mention in your first sentence). It seems to me this article does the opposite.

Personally, I can't think of any kind of capitalism that is compatible with policies / goals / objectives related to:

Tax justice for social ecological justice

or

Redistribute land, labour, capital and resources within and between countries

or

Direct activism and sabotage For example - anti-capitalism malware program

or

Restrict platform capitalism (e.g. AirBnB); Promote decentralised platform cooperative models

etc

(found in the Appendix A. Thematic synthesis of degrowth policy proposals)

For me degrowth is potentially one way to get rid of capitalism.
