I found this in the license agreement for the JetBrains products:
12.8. You declare that You have had sufficient opportunity to review this Agreement, understand the content of all of its clauses, negotiate its terms and seek independent professional legal advice in that respect before entering into it. Consequently, any statutory "form contracts" ("adhesion contracts") regulations shall not be applicable to this Agreement.
Can they legally exclude the "adhesion contracts" regulations which are in place (at least AFAIK) for contracts exactly like these?
If it makes any difference: They state that the governing law will be that of the Czech Republic.
