Note the different scales. They were really floundering and never got up to anything like their intended altitude. They also continued the crazy-low altitude for over 5 minutes before final impact.
This is obviously speculative, but I’ll be curious to find out what happened.
It's certainly not impossible that there was an obvious fault before V1, but it's _way_ down the list of likely scenarios.
I have heard of issues that were discoverable before V1. Famously there was the Russian hockey team that was killed because the pilot was riding the brake and didn’t abort in time.
