@DisabledDem @sleepyknave Some but not many. In practice the biggest barrier is that an enormous number of people don't know about it (there is zero public education on this resource as far as I can tell) and more still have been misled by the recent reporting about "no more free tests".
@DisabledDem @sleepyknave 一些但不多。在实践中，最大的障碍是大量的人对此一无所知（据我所知，对这一资源的公共教育为零），而且最近关于“不再免费测试”的报道误导了更多人”。
