Don't apologize, you have the right to have an opinion. What is not normal here is people attacking you on that very thread for your seniority (or lack there of), this is absolutely shameful.

Bon courage, tu n'as rien fait de mal. Je pense que ce genre de "rant" est mieux adapté à un blog ou il est clair que c'est juste ton opinion et pas celle de l'employeur.
