How much did regulation and taxation and red tape play into Roomba's inability to compete?
What sort of VC deals were they shackled by, in order to siphon off the data and abuse it for third party marketing, and other forms of enshittification?
There's a lot that American companies have been held back by. Some of it is actually good, consumer protective and well crafted, but it won't work if you allow other players in the same market to ignore the regulations and restrictions without consequences. Other policy is just stupid and self destructive, and other policies border on malignant, deliberately giving foreign companies significant advantages, directly and indirectly, without any other purpose.
American companies are way too easily forced into a race to the bottom dynamic, resulting in failure and huge wastes of money and effort.
