There is no disagreement. In the constitution, isonomy is just the principle that says everyone is equal before the law, everyone is subjected to the same rules. That's formal isonomy. Under the constitution, isonomy means you have a proportional right to answer the other party's claims and even extract damages. It does not mean you can have those claims censored. This is literally spelled out in the text. They get to say whatever they want, and you get to answer them and sue them if you want. After the fact. You don't get to preempt it with a priori censorship. That would mean the manifestation of thought is not free.

Plenty of lesser laws expand quite a bit on that concept until it becomes material isonomy. Treating the unequal unequally. They all boil down to things that reduce inequality such as affirmative action. Those are irrelevant to this discussion. TSE's notions of "economic power abuse" no doubt fall in this category.
