Since 1.0 we have the ‘true offline’ mode.
Every single version of LE since that happened is available on the Steam Database, as Steam saves every single version individually for posterity on their servers actually.
So this is available actually. Just every version before true-offline was introduced is lost to time as it needs verification of the servers and hence cannot be started.

This is a quick guide on how to do it. It’s a hassle to not be a inherently integrated function with a user-friendly UI… but it’s doable.
As for the other stuff:
EHG had literally years to act before it came to those issues. That’s the problematic timeframe, and why they deserve backlash for it.
The salvaging part afterwards has been done decently well. It was not acceptable to ever come to that. Had EHG shown as much competence in adapting their approach as they did to salvaging their product as a last hail-mary attempt then all the issues related to it wouldn’t even exist.
It includes undue expansion of the company.
It includes false primary focus.
It includes the absolute neglicence to not design any long-term revenue streams properly.
It includes the focus of expansion over solidification.
Each of them had a major impact… even a single one of them would’ve reduced the severty by postponing the situation for months, allowing to tackle the others respectively.
None of them were handled appropriately.
Downfall is easy to excuse when it comes from a single source.
Downfall is unexcusable when it comes from several places at once.
Why?
Because you can easily overlook a single… or two vectors of failure. But doing so with 4… 5… more… that’s simply hubris of some kind happening.
