Have we reached a point yet where companies are spending millions a year on software licenses, cloud and AI to the point where the return isn't worth it?

Years ago I did work for a company that was spending over a million on Oracle product licenses and I was part of the consultant team they hired to rip it all out and just go for simple maintainable code based on open source products. Not only did it transform into a codebase that the average newly hired developer could maintain, you also had the savings of not paying Oracle a significant portion of your revenue.

I feel like that will repeat itself in a few years time with the current cloud and AI train everyone is on.

I haven't been in a professional setting for a while, I just code for fun nowadays so perhaps I'm somewhat out of the loop.
