Downvoting isn't really a mechanism to censor, flagging is. The intent of downvoting is usually just disagreement. My guess would be you're being downvoted for a few reasons:

- A few of the people you mentioned are somewhat polarising, so folks who dislike them, might downvote

- in a measure of a president's efficacy, mentioning people who think a president is ineffective isn't as convincing as say mentioning actions of the president that were ineffective. You will, for any president, be able to find a large number of people who will passionately argue for/against that president's effectiveness.

- Your sources are very long videos, which discourage verifying if folks want to see what they said about him. Eg "Here's why he's in effective: [3 hours of podcasts]"

- One of your sources is a podcast which features Trump himself, which greatly brings into doubt the objectivism of the video

- the Zuckerberg short is very speculative, further weakening this collection of sources
