Female scientist here.
The backlash is repugnant, however the initial viral reporting was inaccurate and unfair to the many scientists (male and female) who made equally significant contributions to the project.
Dr. Katie Bouman didn't lead the project. She was co-leader of one of the 4 teams who carried out the imaging part of the project. These twitter threads clarify contributions, and also what started the viral reporting:
twitter.com/sparse_k/status/1116785802367918080 by Kazu Akiyama, one of the Imaging Working Group coordinators.
twitter.com/thisgreyspirit/status/1116518544961830918 by Andrew Chael, who co-lead one of the Imaging teams with Katie Bouman.
I'd also suggest looking at the Event Horizon Telescope Organization web-page to get a feeling for how big science collaborations are structured. There are 2 senior women on the Science Council (Sera Markoff and Feryal Ozel), various female Working Group Coordinators and lots of female PhD students and postdocs actually carrying out the instrumentation, data collection, processing and analysis (who aren't listed on this page since it's a ~200 person collaboration).
