As an engineer I can attest that it is also useful for quick calculations and illustrations, especially at the concept stage. We also ran process “simulations” in it for fun, but of course something like SciLab would be better suited for it. The possibility to simultaneously work in the same spreadsheet was also a godsend during lock-downs.
To be fair, business development wasn’t the main hangup for many of the people I know. The two main reasons I heard (and partly raised myself), was firstly the detrimental effect on expanding solar- & wind-energy-production. And secondly overreaching, i.e. not limiting the protection to the environment, but also include townscape protection and historical sites, essentially further restraining residential development (including changing them into more dense usage) in a time where living space is scarce and expensive.
When the pro-side has its reservations, then of course it doesn’t help that the executive (Federal Council) is dominated by pro-corporate ideology and have brought forward arguments of “damaging the business location”. But making it out to be the only reason is just dishonest.
