The 100Mbps bandwidth cap is not great, but at least it is not 50Mbps like on the Oracle Cloud free instances (which they do not mention anywhere and customer support will play games with you just not to admit it).

That’s missing the point. Most folks don’t fully saturate the pipe ~2.6M seconds a month, but it’s trivially easy to max out a 100Mbps pipe for bursts.
