When IBM purchased Ustream, it was pretty clear where they were headed. You can hardly find an internet service that is not subscription based and IBM is following that model. Their focus is on the "big bucks" accounts (business/professional/corporate) and discontinue the free ad-supported accounts. It's a loss for the "little guy", for sure. There will be two plans: professional and enterprise. A professional plan costs $99 up to $999/month (100-5000 streaming hours depending on the plan you chose) Clearly, most of those with free accounts cannot afford and/or justify such a high subscription fee. Unfortunately, the options for an alternative to IBM/Ustream are very limited as far as I can tell.
Facebook Live has grown by leaps and bounds, but it is not without its limitations. Some that come to mind are the lower video quality and time restrictions (I think there is a 4-hour limitation per stream) All streams would have to be generated through the EoE facebook page and viewed on FB. I am not aware of a way to embed those streams to a website as I write this.
YouTube live is also very popular now. The video quality is top notch and can be embedded. However, unlike Ustream, each YouTube live stream has its own embed code, so keeping a website updated with the current live streams would be very time consuming and a lot of ongoing work.
Livestream is subscription based and has never been an affordable option.
Not good news for individuals or small sites..... but the days of anything for free on the interest are pretty much history.
