I have also worked on drum brakes and mostly agree with your observation. The "however" is that Continental has designed a sealed drum brake. Granted this design specifically mentions the electronic parking brake application, it is used for rear-axle braking in EVs because about 80% of the braking power is via regenerative braking. Coupled with about 30% of the braking power being supplied by the rear axle, the design works for this application.
Continental is working on a front-axle drum brake application.
Negatory. Shopify chose to do business in the United States (or any other country) when they could have either geo-blocked IP addresses or not allowed goods or services to be delivered to that country. In the United States (and true for many countries), a company has to register as a foreign corporation (other countries use different terminology or legal structures) in order to conduct business outside of the jurisdiction they are registered. One reason is to have a "registered agent" where they can be served with legal documents.
If we followed your logic, then countries are essentially giving up their sovereignty to the company as there would be no mechanism to enforce laws. GDPR--gone, Food safety regulations--gone. Perhaps your country requires payment processors collect some national tax. Some foreign company can decide not to collect said tax because they are an "international internet site" and your country's rules do not apply to them. I don't buy the libertarian pipe dream that consumers will magically bind together to punish misbehaving companies. The number of times that has been successful is small.
International business is conceptually similar to a property easement. Your neighbor (or a utility) might have the need to use part of your property. An easement that defines that need becomes part of the deed. Similarly, a foreign business wants to operate in a jurisdiction. The national and local laws that define how that occurs and sets the parameters for that operation.
The onus is on the business to comply with the laws in the areas they want to operate within.
Your program is sick! Shoot it and put it out of its memory.
