Anyone who has a list of argument that have proven to increase the popularity of Linux usage in countries? Example like Windows products are banned in China or similar.

He can focus on solving the technical problems. Like have a list of things that has to be done in order for people to be happy with it. Missing feature? Starting guide? Limit what features can be used? C to Rust converter? He does not have to solve it alone, like he did with git. He just need to decide the direction.

Good. Competition is good. If they suceed or fail just means we learn and build a better product.

Not leagaly but users will be frustated and leave. They will rollback within a day so you will not need to worry too much.

No ads. Lightweight app/website.

Maybe it is just avoiding big tech.
