Everything you read outside of your company official announcement are considered rumors. (Your management will even tell you so - don't believe in rumors and let's focus at your work). It is up to you who you believing in, your management or this site. From experience, I believed the rumors here. Take your pick.
Second, it rather childish to say after reading 'rumors' from this site, it got you worried. The fact is, what can you do about it? If you are part of the layoff list, then you are part of it. You either look for new role or wait for the severance package. Are you counting on this site to determine what your next move is? If you want to listen to 'true' information, go ask your VP.
Take the information here as a grain of salt, you might worried lesser.
