Tor Browser helps provide security and privacy while browsing the web, by masking your IP address. Though it’s unlikely that governments presently monitor traffic to Stop Fossil Fuels sites, the danger will increase if and when the environmental movement becomes effective. Those considering underground action would be wise to protect themselves by browsing sensitive content only with Tor, and even those committed to aboveground work may feel more comfortable obfuscating their web activity as a precaution against future backlash.
Internet users with nothing in particular to hide still benefit from Tor and other privacy tools. Corporations surveil us constantly, mining our data—our digital identity—to sell to advertisers, insurance companies, governments, and any other interested entities. If you’re using a free service, then you’re probably the product.
Most importantly, the more people using Tor and other privacy tools, the less unusual will seem underground activists, and the more difficult it will be for governments to break the systems. Use Tor and other digital security tools whenever feasible. Encourage others, even non-activists, to do so.
If you’re technically savvy, consider running a Tor Relay.
