Marco Falke, who has been with Bitcoin Core for the past 7 years, decided to leave the project because he felt it was no longer suitable.

According to Wall Street Journal, Marco Falke is Bitcoin Core’s most prolific developer in his seven years of work, making over 2,000 tweaks to Bitcoin’s code.
However, on February 21, the veteran programmer suddenly announced his resignation on Twitter:
“I have been a maintainer and verifier of Bitcoin Core modifications for about 7 years now. In a difficult decision, I have chosen to end my role as a maintainer.”
Still, Marco Falke reaffirmed his passion for Bitcoin and said he remains “optimistic about the future” of the currency, but perhaps his role is no longer relevant.
In 7 years of work, 3 years Falke was funded for his contributions to Bitcoin Core, these funding came from crypto exchange OKcoin and investment fund Paradigm. However, last month, two investors said they were adjusting the one-year allowance for Falke.
Over the past 18 months Bitcoin Core has seen 5 key maintainers say goodbye to the project, preceded by John Newbery, Samuel Dobson, Peter Wuilleand recently Wladimir van der Laan.
Thus, the Bitcoin Core maintenance team is now down to only 4 people, Hennadii Stepanov, Michael Ford, Andrew Chow, and Gloria Zhao, responsible for overseeing the code behind the world’s most valuable cryptocurrency network.
This succession of departures has raised concerns about the internal situation of the project. That could come from the pressure of maintaining the prestige of owning access to the world’s largest coin, coupled with the regulatory tensions surrounding it.
