This specific complaint seems to be about data privacy, not about a freedom being eroded. Also, since you can fork it, as has been previously mentioned, there seems to be no purpose in objecting to this type of FOSS acquisition. Worst case, the project ends as it was before the acquisition, with no corporate support or funding whatsoever, at which point it seems it won't make any difference whether there was a complaint or not.
