As the owner of many domain names, I do not want to see price-caps removed and believe price increases would be unfair. 
Further, legacy gTLDs are fundamentally different and registrants of legacy TLDs are entitled to price stability and predictability, and should not be subject to price
increases with no maximums. Unlike new gTLDs, registrants of legacy TLDs registered their names and made their online presence on legacy TLDs on the
basis that price caps would continue to exist.

Removing the price caps will cause an speculative increase that cannot be predicted. One year i can pay 15, and the next year 150. 
This is unbearable for many of us that do not make the use of domains a commercial activity.

Best regards,
