Mitchell Baker, chairwoman of Mozilla, called on Friday for more transparency into targeted advertising, including ads targeting followers of President Donald Trump.
Social media helped fuel the chaos in Washington DC on Wednesday. Now, it's important to know who has been paying for targeted ads, how much they've paid, and who they've targeted.
That information should be made public, Baker said on the official blog for the Mozilla Foundation and Mozilla Corporation.
"Donald Trump is certainly not the first politician to exploit the architecture of the internet in this way, and he won't be the last," Baker wrote on Friday.
