I agree, the moment the drop started it was abusive power-selling, similar to the infamous incident at the $960 ATH - but with more plausible deniability, with cover given by the coronavirus and the fake China sales report by Bloomberg.
So yes, IMO options writing Nasdaq Market Makers performed a major (and illegal) bear raid, with the naked shorting of millions of TSLA shares - even after the uptick rule was in effect.
This is flaunting SEC authority and regulations to such a degree that it might make sense to file an investor complaint if you held any TSLA shares, long calls or short puts:
In the description, beyond the accurate identification of accounts and sums, I'd write something like:
On or about February 27, one or more Nasdaq Market Makers launched an illegal market manipulation scheme using "naked short selling", to illegally profit from proprietary trading positions they took in the TSLA options market.
This scheme is visible through the abnormally high "short sale exempt" transactions that happened 13 trading days after an anomalous spike in "failure to deliver (FTD)" shares indicative of naked short selling.
The market manipulation was performed via very aggressive sell orders that bid down the price not with the intent to sell effectively, but to mark down the price illegally - which is inconsistent with any non-proprietary "market making" role.

As an investor I was financially harmed by this illegal market manipulation scheme.
Estimated harm to all investors is probably in excess of 15 billion dollars in lost market cap, in addition to unknown losses by long call and short put options holders in the TSLA options market."
It makes sense to file a SEC complaint even if you think the current SEC administration won't take enforcement action: these complaints get archived, the transaction logs don't go away, maybe a potential Sanders administration, reportedly not a big friend of Wall Street, will give the SEC some real enforcement officials.
