Freedom of speech is undoubtedly one of the cornerstones of modern democracy. It allows for open discussion, critical thinking, and the sharing of information that might not be heard otherwise. As such, it's imperative to preserve it at all costs.

The emergence and dominance of big tech companies over online discourse has opened up new risks to freedom of speech through their power to censor people and remove content arbitrarily under vague community guidelines. This may lead individuals and groups to self-censor themselves out for fear from retaliation in this BIG Tech social media ecosystem we live in right now.

Many believe that modern cryptography plays a crucial role here as censor-resistant setups are more robust against these central attributes recognized as significant problems today separating us from autonomy over our published ideas while enabling arbitrary control over what is shared with humanity worldwide inside well-established channels dominated most by global private corporations instead by public ones securing Speech Freedom presented goods.

However let´s remember: With Power Comes Responsibility- Where possible there should be no need for inscrutable decision-making processes taking place with much less or absent accountability at this extent global networks currently operate beyond freedoms traditionally associated ultimately aiming harmony through current very painful regulatory construction.This being said prevention does become key as crypto systems can help there yet regulation falls upon those responsible agents publicly elected so choose censors or overt dissimilatory constructs negating itself eliminating Freedom-of opulent critique-&-speech acting consequences unresolved hence present matters universal jurisdiction."
