I do agree with you: there are other discussions in France and outside France, more sophisticated and very legitimate. Yet, the post follow not only the numerous media articles but also MANY discussions in social media (including my feed) where the four points mentioned came again and gain. 
I don’t aim at refusing postmortems and learning lessons. Only to avoid wasting energy & coming to the wrong conclusions.

By the way, if I do agree with your 3rd point (roadshow is about delivering good news and consistent growth), I am reserved about your first two exemples:
(a) I don’t think the story behind Save is (only) about managing growth. If that’s your takeaway about Save, you might make the wrong choice tomorrow (don’t rely on public intel). And I’m convinced that i. their next announcement will deliver amazing news, ii. it is not obvious that they should have done what they did another way, maybe they should have build sooner their internal control tools but certainly not to lower their growth to have everything under control.
 (b) many (most?) startups don’t really have the choice, they need to chose between spectacular growth or financial autonomy. If they chose to lower their dependency on external funding (VC & other type of investors), they chose to mitigate your risk and… reduce their dreams. We can choose to build a company more focused on revenue -in the revenue/growth tradeoff-, that is a very reasonable and fair choice, but that’s not the way to build world champions. And I would feel it regrettable to present this path as a lesson learned toward success.
