The real crime was the predatory lawsuit DC pursued to drive Fawcett out of business because they could't surpass Captain Marvel's sales as it was outselling Superman and so did whatever they could to bring down the competition.
And don't forget, before Marvel picked up the trademarks (not copyrights) to the name, the comic world was blessed with this Captain Marvel in the swinging 1960s...
from MF Enterprises.
DC's lawsuit against Fawcett was in 1951. They didn't show any interest in the character or the rights until 1972 when they licensed the character form the remains of Fawcett, and 5 years after Marvel introduced their Captain Marvel. DC didn't want the character in the 50s or 60s, their goal was to get him off the newsstands to protect Superman sales, not to get another character. They didn't purchase the rights outright for the character until 1987 and from '72 to '87 their use of the characters was limited as they had to pay a per use fee to Fawcett whenever they used one of the characters they licensed from them.
There's no tragedy in DC not getting the rights to the name or whatever, the tragedy was the fate of Fawcett itself and DC's predatory business practices at the time. DC simply reaps what they sowed there.
