There are several factors. - They mainly fear prosecution after the protests and the travel card as a evidence of their presence. Cell tower triangulation fair worse in court. - Many people are also using burner cards which are easy to purchase in Hong Kong. - The protest was decentralized and was mainly organized with internet forums and instant messaging software. Not using a travel card is only a mild inconvenience.

Burner SIMs or burner phones + SIMs? As long a the government can link the IMEI to a person there's not much anonymity bought with a burner SIM. Using a burner transit card isn't nothing, but there's pretty good surveillance infrastructure in place already (e.g. the hospitals).
