The banks contacted the government to seek advice on what to with these funds before the Emergency Act. They have these funds they know belong to multiple individuals, including the account holder, and don't know what to do with them. Just because 100,000 people dumped money into your account for cause doesn't mean it belongs to you personally.
No individual protestors accounts have been frozen. If you donated to this cause you literally have no idea where your money went. If you participated in the protest and feel entitled to these funds, how would you get them? Freezing the accounts, at this time, is neither pro-protest or anti-protest. The government isn't seizing this money -- it's keeping it from being moved until somebody can figure out who even owns it.
