| Hi! Tool author here. Almost every single open source compression tool contains a clause like this. For example, the one in the README that you see has been directly lifted from the bzip2 README. Almost all open source projects come with such a no-warranty scheme. 7-Zip, zstandard, xz-utils, etc; as exemplified by a quote from the license text of the MIT license: > THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR
IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY,
FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT. IN NO EVENT SHALL THE
AUTHORS OR COPYRIGHT HOLDERS BE LIABLE FOR ANY CLAIM, DAMAGES OR OTHER
LIABILITY, WHETHER IN AN ACTION OF CONTRACT, TORT OR OTHERWISE, ARISING FROM,
OUT OF OR IN CONNECTION WITH THE SOFTWARE OR THE USE OR OTHER DEALINGS IN THE
SOFTWARE. If you were willing to sign a commercial support contract with me on terms that we negotiated, I would be willing to provide you warranty. If you were not aware, this is essentially the business model of WinRAR. The reason why tools like 7-Zip are not used by the public sector or companies (at least here) is that they provide no warranty in case of data loss. However, if you actually buy WinRAR, then you can hold them liable for damage to your archives. The "infinite 40 day trial" of WinRAR does not entitle you to compensation for damages and thus corporate entities and public entities have to buy WinRAR licenses. WinRAR has never cared about personal customers. In general, having to cope with mild reliability of software is what you have to live with - you already get more than you paid for. Not to say that my tool is unreliable - I put a lot of effort into it, but it would put you in bad light to complain about something that you generously received for free :). |
My point was more if you went into a store to buy some cereal and you had two options: "Cornflakes" and "Cornflakes 2 - they're better!" but you noticed that while both packets had standard legal nonsense on them but Cornflakes 2 had "This cereal almost certainly does not contain broken glass" as well, personally I think human nature would make me go with the packet that didn't bring up broken glass in the first place - even if both of them have the exact same chance of containing it
