Wow, how fix (WITHOUT intelligence tests as voting requirement) :(
The real issue is that western societies are built on individualism and the is that everyone is equal when they are obviously not and this would expose the lie.

However, the real issue is that decisions are packaged together. People vote for a party which they agree with on a few issues (or just one) and the rest become the noise.
So we need to split voting by issue. You could have one vote to determine which issues people care about most, then have multiple separate parlaments - but there would need to be a mechanism to force them to only write laws for the specific issue which is hard.

We could also allow people to override the votes of their representatives. The more people vote directly, the less weight the representatives have.
The saddest part is this is to the detriment of literally everyone except a couple rich owners of those companies. And everyone has the right to vote. But western democracy is so indirect the people who understand and care have no way to change the law because their signal is lost in all the noise by those who don't know or don't care.
If the vote came down to people in favor of walled gardens or in favor of forcing companies to open their platforms, with everyone else not voting, it would be a landslide. But there's no way to vote on it this way.
