Now in bad times, it's considered "prudent," because everyone is under financial pressure. Laying off people preemptively wins in both ways in that in can look like you're eliminating financial pressure when everyone is worried about it (as opposed to the good times, where you will be singled out), as well as being able to get rid of the lowest performers and reducing pay of everyone else while avoiding bad PR, and even being considered good because you're still employing the rest. As long as the business remains solvent it's a win-win for the company.
Not saying this is good or bad for the economy or the employees, but just reflecting on some of the game theory of this.
Such a crisis is a good moment to slim down the workforce since it is a legitimate restructuring and it avoids any image harm. and it's not just low performers that suffer sometimes. An average performer might get caught in the net if the pay/performance ratio is not good. Many good performers also do just because the area they worked in is not deemed profitable or necessary anymore.
This is a confusing question, seems the answer seems embedded in the question...the former signals that there's "financial pressure" on the company over and above the reasonable baseline that every company faces, while the latter doesn't. A 100% financially healthy and secure company may choose to pay the ongoing cost of restructuring during good economic times, since layoffs in good times may have PR costs (for recruitment, for example) that outweigh the carrying costs of the low performers (or unbalanced departments, or whatever). If a downturn lowers this cost, then you'd expect companies to take advantage of it.
The comment above yours is basically saying: #2 might not be the case, especially with only 8% being laid off"
Evidence against this is the fact that they also laid off lidar engineering staff in Pasadena; I don't know Cruise's business, but this also seems like the kind of consolidation you'd expect a relatively healthy company to do (though "healthy" is a weird word for a pre-product R&D co).

A broader economic crisis offers good cover for such an action. If everyone is laying employees off, it's not as bad if you do it too.
1. Whether the company might cut deeper later
2. Whether other companies will be forced to follow suit
3. Because of 1 and 2, whether the average HN reader should worry about their livelihood.
(HN readers are, of course, 100% high performers their employers are lucky to have)
