For the reasons stated in other places. Seeing a company that's cutting a large portion of their workforce is just bad optics. Yes, YOU may perceive it as wise business, but those who are looking to have a job in a year might not feel good about hiring on with a company that just had a layoff of a significant part of their workforce. What's to stop them from laying you off when their new plan doesn't work out as well? Companies that are doing well do not do large sweeping cuts.They tend to do smaller more precise cuts. This one seems like desperation.
If you need to make people redundant for business reasons then you need to do it.
It's not careless to do something that needs to be done. What should they do instead? Try to conceal the layoffs? I think that's illegal in most jurisdictions.
And they also cannot stop hiring.
All the actions here are rational and as carefully done as they could be.
