Reddit is getting worse and worse. Not sure what happened, but it started losing it's way around 2014-2015.

It's probably because those with decision making authority have no idea what open source is and how it works.

Huawei is not the only one. Almost all software companies have some KPI that employees are farming. (speaking from experience here)
