All the major clouds are suffering from this. AWS you can't ever get an 80gb gpu without a long term reserve and even then it's wildly expensive. GCP you can sometimes but its also insanely expensive.
These companies claim to be "startup friendly", they are anything but. All the neo-clouds somehow manage to do this well (runpod, nebius, lambda) but the big clouds are just milking enterprise customers who won't leave and in the process screwing over the startups.
This is a massive mistake they are making, which will hurt their long term growth significantly.
