Perhaps business-hostile isn't the best phrase, but their terms let Gandi stick their nose in areas which normally would be civil matters between a domain holder and a third party. For example, Gandi reserves the right to terminate your domain without notice if a third party notifies Gandi that you are involved in:
"any infringement of applicable law in any way (for example
using an automated script)" [section 12.2.1]
How familiar are you with the laws of France, under which this agreement has jurisdiction? Is your business a search engine and you have automated scripts which crawl websites, collecting information? What if collecting, storing, or displaying that information violates a law in France? Are you running some kind of bitcoin-related service and is it compliant with money laws in France? What if you have a ride-sharing service? Are you sure you're not running afoul of taxi regulations? In any case, I hope you have a lawyer who speaks French:
"Only the text of the French version of this Contract
shall govern in the event of a dispute of interpretation
of the present Contract."
Did someone file a copyright claim against content your users posted? Are you doing anything Gandi deems morally objectionable? Gandi could shut down your domain. More info: https://news.ycombinator.com/item?id=3405177
Our legal team says:
"You have obviously cut a big part of the article of Gandi's contract. Many registries which operate new gTLD's are entitled to cancel domain names at their own discretion in the light of their national laws (many German registries retain the right to suspend domain names if they do not comply with the laws of the Republic)."
