Totally valid criticism, I absolutely agree with you. Times are tough for trans folk and giving money to transphobes is not helping that.
Looking back on it, I wouldn't buy it having seen how far off the deep end she has gone. I admit I dismissed her at the time as just a nutjob on Twitter but she's now proved to me that she is a bigot beyond reproach.

I run mine on a Intel N100 based mini PC from Beelink running Proxmox. It's just about the only thing it does at the moment so I've had no concerns about bottlenecking.
It's much more powerful than a pi and costs a not too dissimilar amount to one after you factor in a case, storage, power supply.
