You end up making a huge amount of people jobless, including the C suite, and investors moneyless.
It'll be a nice reminder for everybody, and everybody will be very picky about which company they work for / invest in. Maybe leading to more transparency in companies so that they can prove that they don't commit fraud / crimes.
Too many companies have so much money/power that their crimes have much worse consequences than making people jobless.
This sounds great. I would definitely love a splitwise alternative in particular!
You may want to think about using another name for your app suite though. Since it may bring confusion with the simple mobile tools (https://simplemobiletools.com/index.html) which for example also have a "Simple Notes" app.
If you kill the company you do punish those people by killing their main revenue/asset. The good thing is that you also punish the investors who will lose all their money. This will dissuade anybody to invest into a company if there is a possibility that the company is fraudulent. This could even push more transparency in the companies to attract investors.
Any decent heating system will have a thermostat which will activate the heating when it's getting cold. Also no need for internet to be able to setup the time when electricity is cheaper. It's not like it's something you need to do regularly. Setting this all up directly on the heating system works well enough.
