Incredible! Web Archive made a backup including the files?!?
How did it do that? How did it find the path /beta90_6ba923?

They don't. Users can create an account on wayback machine and say them to archive specific files or web pages:
Go to this site and check the edit box on the bottom right corner:
Or directly go to this page:

Get it while it lasts. Especially now that it is publicly shared here which is monitored by Hex-Rays, and I imagine they even check the non public parts via a registered account, so they will almost surely get hit with DMCA takedown notice within days.

How many people chooses Ghidra/Binja over IDA Pro with full decompiler? Even though this is a leak, I though hex-rays people are purposely slow (and they are ok with the leak. They will still get new customers). They are dominating the field! What do you think?

don't want to be over-paranoid but this story sounds like a well organised CTF. A stupid error left the beta for free to anyone without an installation pwd, an old pwd protected zip file which they surely know can be fixed using bkcrack, the DS-Store trick and lastly the web archive trick .. everything smells a bit strange if you consider who they are..

Using both Ghidra and Binja as well as Cutter and gdb, this race to get latest iDA is non sense to me

what's new in Ida 9.0
this one is interesting "A custom Hex-Rays licencing server replaces the FlexNet licensing server for floating licenses"

Btw. this guy have youtube channel with nice IDA tutorials.
