  • core-js

    Project mention: Users are massively giving their 1-star reviews to AdBlocker | | 2023-11-30

    Funny you say that, I was just thinking earlier today back to the core-js drama.

    In short: the creator of a NPM package that is used by approximately everyone, everywhere, was facing a legal battle. He had been developing this package full time for years and did not have the cash on hand to hire a lawyer. He added a console log that ran on installing his package that said something like "If you're using core-js please consider donating". Queue an absolute shitstorm of people screaming at him in the github issues and him going to prison for around 10 months. Luckily he seems to be back on the grind nowadays, with a decently robust cross-platform slush fund to boot (~200k USD across Pateron, Open Collective, Bitcoin).

    It can be a rough world out there for the folks building for the "focus, productivity and anti-distraction" platform.
