The idea that companies would never give anyone 2 weeks notice is probably closer to reality than the inverse of that assertion.
You call it generous, Germany calls it the law (depending on tenure, with some other European countries having a similar timeframe), and somehow non-FAANG non-tech companies are also able to stomach it. This is obviously very influenced by a very high demand for stability in Germany, but I also find it crazy how little people in other countries expect from their employers.
This is significantly less generous than FAANG layoff severances.
Anecdotally, for experienced devs, it is something that is commonly demanded and granted. For entry level positions it's quite common, but more and more people are asking for it quite early in their careers (even outside of tech).
However, I think you're going WAY too far in the other direction to suggest that "no severance" or "only two weeks of severance" is closer to true than not. I've seen a lot of mid-sized companies give 30 days of severance.
