If anything the skew within the platforms is to prioritize pro-palestinian views https://twitter.com/committeeonccp/status/173279243496103143...
It also seems like these platforms create (rather than support) anti-Israeli views: https://twitter.com/antgoldbloom/status/1730255552738201854
US views skew pro-israel, and GenZ is closer to 50/50, so if there's something going on online, it's not in favor of Israel.
It's probably relevant that there are 1 billion Muslims to 16 million Jews, and that the largest relevant population of pro-Israeli internationals is India and Indian Hindus, and they are not on TikTok (blocked in India).
I think it is currently about an order of magnitude more civilians deaths have resulted from the actions of Likud (Netanyahu etc..., who control the government and hence the IDF) than from the actions of Hamas. IDF is apparently disrupting civilian aid, destroying infrastructure including hospitals, and causing mass population movements into areas that cannot support them, so the risk of death from starvation and infectious disease at a massive scale as an indirect result is high. The Likud-controlled IDF are also apparently enforcing a 'lock down' of Palestinian civilians in the West Bank while allowing Israeli citizens to seize land by force and further expand the occupied territories.
So the scale of the atrocities seems to be much higher on the Likud side than the Hamas side, covers both the West Bank and Gaza, and it makes sense that the Palestinian victims of those atrocities would receive more support. That doesn't mean that all the people who care about the plight of the Palestinian population are anti-Israel (they are just not posting about it because they are likely prioritising issues).
* There really isn't any better deathrates when the other side is explicitly based on indifference to its own civillian casualties. Mosul had 40K civillian deaths in a 2.5x smaller city (by population)[0]. I fail to see why Israel can't use the same legal tactics** the US used to defend itself versus jihadists, except the Israeli death rate is lower and the US had far less justification.
* Focusing on the Likud is a mistake. Every Israeli political party would have counterattacked at Gaza, with about the same (legal) tactics, but probably much more aggressively. Leaving next door to a genocidal terrorist regime was unacceptable, actually moreso to the Israeli Left. After all, what's the point of two states if the other side can do _anything_ and get support afterwards?
And I mean anything - the attack was into 1967 lines, deathrates much higher than in Gaza. The irony is that many people that say they support 2ss are trying to enshrine impunity here, basically destroying any hope that either side will support 2ss. That's why Bibi was the pretend 'cautious' here, because of very cynical calculation - Hamas staying weakened but alive lets Bibi kill 2ss - WB Palestinians flock to 'victorious' Hamas, while Israeli Left approach is discredited - but his hand was forced.
* Focusing on Hamas is also somewhat of a mistake, given polls show widespread crosscutting Palestinian support to Hamas action[1].

** When we ignore scaremongering about 'starvation/disease at a massive scale' when it's not happening, the only thing the list has are actions into hospitals which even the US believes are used by Hamas.
